Chevy S-10 IAC throttle body diagram?
The IAC is a small motor on the throttle body that screws a giant needle valve ("pintle") up and down. It regulates how much air is allowed to bypass the closed throttle plate, thereby controlling the idle speed. It moves up for example when you turn the a/c on, to kick it from the usual 900 to 1100 rpms. It's movement is controlled by the PCM (powertrain control module), to maintain the desired idle speed.
There is not much to the throttle body... the throttle plate itself, the IAC motor (idle air control), attachments for vacuum lines, and a TP (throttle position) sensor to tell the computer what percentage the throttle is open.

How do you convert throttle body to carb on a 89 Chevy Caprice?
you would have to get a carbeureted manifold and a non-computer-controlled-distributor. then you have a choice; you can keep your current heads and cut the four middle bolt ho…les on your new intake out to the edge so the bolts will fit, or you can put an older set of heads on it (older heads have bolts around the edge of the valve covers instead of through the middle). after you have bolted all these parts on with new gaskets, you have to run a positive (that comes on with the ignition switch) to the distributor terminal marked +. that should make it run, but your fuel pump will switch off after about a second. you will have to solve that problem by either wiring the fuel pump the same way you did the distributor (on and off with the ignition switch) and installing a fuel pressure regulator, or removing the fuel pump and running an aftermarket electric one or a standard manual one that bolts to the block. I am doing a swap of a 74 350 into an 89 scottsdale and i kept the serpentine belt system with the a/c pump, power steering, and stock 89 alternator. it is working so far, but i still have not solved the fuel issue for lack of money and lack of knowing which way is best. if you come up with any info on the fuel issue, please email me (benson-stacy@hotmail.com) thanks and good luck.

Automotive Throttle by Wire Problems
Automotive throttle by wire systems have come a long way in the last five years. Although the system is now more reliable than first-generation systems, there remains plenty o…f room for improvement. Here we'll discuss how Electronic Throttle Control (ETC) works and review common problems associated with automobiles that utilize the technology.Automobile manufacturers have been chomping at the bit to roll out electronic actuator controlled throttle systems for decades. The advantage from their point of view is the ability to remove the driver from throttle decisions in certain situations. Things like [smart cruise control](http://autorepair.answers.com/accessories/how-to-use-cruise-control-features), stability safety systems, traction control and [anti lock brakes systems](http://autorepair.answers.com/autorepair/abs-system-common-complaints) are now able to close the throttle when necessary. Although this is essentially ignoring the driver's request it enhances safety in panic situations when drivers are likely to make poor decisions.Electronic throttle control replaces the manual cables that use to connect between the gas pedal and the throttle plate. This physical connection is now completed using sensors, wiring and a control module. To be more specific, they mount a throttle position sensor in the gas pedal. This variable potentiometer sends the current throttle position to the control module where the signal is analyzed. From the module, they send voltage to a control motor mounted in the throttle body. This actuator carries out the command to open the throttle plate, thereby allowing more air to flow into the engine. The action increases RPMs and power output. Using the control module as the middleman allows the computer to use other input variables in the decision-making process. As an example, the cruise control system no longer needs the [complicated servos and actuators](http://autorepair.answers.com/accessories/diagnose-and-repair-cruise-control) since the computer is capable of holding the throttle open in the right position when the cruise switch is activated.Like many new systems the electronic throttle control has hit a few bumps in the road. For General Motors the problem has been most evident on their full size light-duty truck line from 2001 through 2009. Problems with the actuator motor in the throttle body or the throttle position sensor mounted near the butterfly has caused a wide variety of complaints from motorists.Warning lights in the dash seem to provide the first clue that something is going wrong. Drivers have reported traction control, service stability track and engine power reduced lights coming on intermittently. Although individual instances of these warning lights will have to be diagnosed on a case-by-case basis, often the failure is a malfunction in the throttle body. Unfortunately the actuator and throttle position sensor that can fail are not serviced separately. Complete replacement throttle body units are in the range of $250-$400 depending on the year, make and model and where the parts originate from.Chrysler products are not immune from problems with the drive by wire system. However, what is different on Chrysler automobiles is they have a separate electronic throttle control light. The ETC light will come on when a malfunction is detected. A check engine light with a throttle position sensor code set in memory can also occur. Also different from GM, the throttle position sensor is replaceable depending on the year make and model. In some cases, motorists will have to tow the vehicle in for service when complete throttle body failure occurs, because the throttle plate will not open.Some companies like Toyota and Audi have had their share of bad press from either sudden acceleration syndrome or throttle control problems where the automobile performed an action that was not expected. The complaints in these cases started to surface before a problem was identified. When Toyota drivers began to complain, the motor company's investigation led them to believe interference with the floor mat was the culprit. In 2002 the national Highway traffic safety administration (NHTSA) contracted NASA scientists to study the issue. In the end they could not confirm or deny that a software problem was responsible for the unintended acceleration or that the problem actually occurred as they were unable to reproduce it in regular driving situations. In October 2013 a grand jury returned a verdict finding Toyota liable in the case of a collision in 2007. In the end throttle by wire systems will make it past these bumps in the road just like [the mass air flow sensor](http://autorepair.answers.com/troubleshooting/help-with-mass-air-flow-sensor-problems) and other automotive components that didn't work perfectly when they were initially launched.

The History of the Chevy Truck
The name Chevrolet is over 100 years strong and is still going strong. Although this auto manufacturer has been building vehicles for over 100 years, its truck division began …in 1918. This brand has become a trusted name in households all around America. Going back in history, the original Chevy factory was in Detroit, Michigan.The first truck actually built by Chevy was not one that was put on the market. It was built on an idea to assist in carrying materials around the factory. It started as a few car chassis that had hand-built beds. Once it was discovered that this in-house model was a great idea, the company began manufacturing for retail sale.The first truck to be built for a customer took place on November 22, 1916. The model was the Chevrolet Four Ninety Half-Ton. This vehicle sold for $595. In those days, the trucks were sold with no body. It was up to the customer to either build or purchase a wooden cab and cargo box or a panel body. Basically, they were purchasing a cowl chassis unit and front sheet metal.The Model T was the second truck built by Chevy. The cost of the vehicle was about $1,125, and again, had no body. This style was built stronger than the half-ton and had a longer body. This truck cruised along at a top speed of 25 mph. The body style of this model was carried over to newer models and remained very similar until the 1930s.After the Great Depression, Chevrolet battled to remain a leader in the auto industry and strived to bring the truck market back to life. This meant that the company needed an innovative edge. Throughout the 1930s, a more streamlined body was designed. These models also included more powerful engines, such as a 78 horsepower engine found in the 1937 half-ton pickup, and a sturdier body that was able to carry heavier loads.By the early 1950s, the auto industry was showing a change. The late 1940s showed the production ratio of cars to trucks at about 4 to1. By 1950, the ratio was more like 2.5 to1 and Chevy became the first car manufacturer to sell over 2 million automobiles in one year. Many of the trucks were used for farming or at factories up until the mid-50s when the Cameo Carrier was introduced. This vehicle became a popular seller and was seen in many suburban neighborhoods.Although the legacy started by Louis Chevrolet still carries the name, this division of autos is actually owned by the General Motors Company. Despite this fact, the name is still a leader in the auto and truck industry today. There have been many models of the Chevy truck over the years, such as the Covair Pickup, LUV, S-10, and the most recent being Silverado and Colorado.The Chevrolet bowtie logo was introduced in 1913. There are many speculations as to why Louis Chevrolet chose this symbol. Some say it may have been influenced by a particular wallpaper Chevrolet saw in a French hotel, or historian Ken Kaufmann says he believes it to be based on a coal company titled Coalettes, and others believe that it could be a symbol of his Swiss background.

Easy Steps to Creating a Leaf Diagram
A stem and leaf diagram is an easy way to arrange values to give basic information about a data set. Especially helpful are back-to-back stem and leaf diagrams, which are used… to compare two data sets. Create your diagram by following the simple steps below.Organize the datum to be used in your stem and leaf diagram. For example, the following eight numbers comprising your data set would be listed as: 17, 22, 24, 26, 31, 34, 42 and 43.The stems are the numbers down the left side of the diagram (or the middle if you are creating back-to-back diagrams) usually consisting of every digit in each datum but the last changing digit, depending on your leaves. Based on the data above, the four stems are the "10s" digits; 1, 2, 3 and 4.The leaves are usually the last changing digit of each datum. In this instance, the leaves are the "ones" digit of each number.A key is used to show what the stems and leaves represent. For instance, one possible key for the data above is: 1|7 = 17. An example of a back-to-back diagram key is: 4|2|5 where x=24 and y=25.The stems in this case (1, 2, 3 and 4) appear as consecutive numbers from top to bottom. Draw a vertical line down the page next to the "stems" to separate them from the "leaves."Each "leaf" is then written in ascending order as a list next to its appropriate stem.For example, the leaves of 22, 24 and 26 from the set above should appear as: 2| 2 4 6.If you are creating a back-to-back diagram to compare two sets of data, you only need one stem for both sets. The stem is "shared," and placed in the middle of the page, with one set of "leaves" on each side.Use your completed stem and leaf diagram to identify basic patterns in your data. Specifically, your diagram allows you to easily identify the median, mode and other quartiles of the data.Stem and leaf plots offer you an easy way to examine the distribution of your data and determine if your data is centered at one or two locations.

This site provides information about how to touch the cervix and tell if you are ovulating. A harder, easy to locate cervix (meaning it is not far inside your body) indicates you are not ovulating.At Pregnology, use the quiz on the site to gather more information about your potential ovulation. The site provides information about the cervix positioning and changes, but also offers a simple calculator to help you to calculate your ovulation period. This is helpful in women dealing with infertility or difficulty in getting pregnant.The American Pregnancy Association provides information about what happens to the cervix during ovulation. This includes the mucus secretions that occur due to the estrogen hormone being present. It also discusses what the changes in this mucus mean. This can help you, along with self-examination, to know if you are ovulating.A cervix diagram is a first step in learning about your body. Understanding the location of the cervix, especially how it changes in your body throughout your menstrual cycle, is necessary to know when ovulation is occurring. Women's health provides may instruct you on how to tell if you are ovulating using other methods, including mucus discharge. However, for those battling infertility, the condition of the cervix is also important.Another common method for testing ovulation is to use the basal body temperature. It tracks changes in your body's temperature and, as a result, can indicate when you may be ovulating. (MORE)
