Code 44 indicates a lean mixture at the oxygen sensor and it couldbe a variety of things from a vacuum leak, a bad fuel regulator, ora bad fuel pump. Also those engines were known for bad distributorshafts. It is best to take it to a mechanic.
intake air temperature make sure it's connected. most of the time people disconnect without thinking about it. like when they install a cold air intake if it is check voltage.on terminal a side, 5-volts with the key on but not running if bad replace
What does the trouble code of P0174 on a 1997 Mercury Courgar XR7 with a V6 engine and how do you fix it?
Answer . Look for a vacuum leak,and clean the MAF sensor:\n. \nI had a vacuum leak at the throttle body, which was part of an assembly ford dealer sells. They dont sell just the rubber elbow I needed, so I optioned to get the assembly and replace the PVC while I had it apart. The vacuum leak at… the throttle body was giving me DTC P0171 and P0174, rough idle and surging. After I had gone through cleaning the MAF sensor and cleaning the combustion chamber, throttle body, and fuel injectors with a professional fuel system cleaning kit from Berryman Chemtool. I found the vacuum leak. I have replace the vent tube and PVC valve. I reset my computer and I don't have any codes. ( Full Answer )
Answer . \nP0455 means a gross leak detected in the Evaporative Emissions System. Some call this a "gas cap" code, because the most common cause a loose or failed gas cap. But it could be caused by any vapor leak in the fuel tank, filler neck, or anywhere else in the vapor management system. If …it isn't a gas cap, you will need tol take it someplace where they have a smoke machine that can find the leak using smoke. ( Full Answer )

How do you fix a recurring number 4 cylinder misfire diagnostic code on a Windstar 3.8L engine after changing sparkplugs and wires?
You may have something wrong with that cylinder that is causing aloss of compression or a loss of combustion on that cylinder. Thosethings were notorious for head gasket deterioration, which causedcoolant to enter the cylinder, leading to a misfire, esp on initialstart up. Also, you may have a fault…y coil tower on your coil pack. I haveseen many coil packs needing replaced due to one coil failing onit. You also have 6 injectors that are fired by the computer. Ifyou have a problem with the #4 injector, the #4 injector circuit,or the #4 injector driver in the computer, that would lead to aP0304 code. Another situation I see frequently: If that engine has individualEGR ports to each cylinder, located in the intake manifold (somefrom about 96 on did), you may have a situation where all but #4are stopped up. What happens is, when the EGR is commanded on, theimbalance of EGR gasses entering the cylinders causes that cylinderto go excessively lean in comparison with the other cylinders, thuscausing a misfire on that cylinder. It is never good to just blow parts on a vehicle when you have atrouble code and a check engine light. You need to determine whatcould cause a cylinder to misfire. The main causes of misfire to acylinder are lack of ignition, lack of fuel, air/fuel to lean tothat cylinder ( a vacuum leak right near that cylinder can alsocause this), Loss of compression, or coolant entering cylinder.Answer WINDSTARS HAVE A COMMON PROBLEM WITH THERE EGR PORTS(IN THE LOWERINTAKE MANIFOLD) PLUGGING UP WITH CARBON -IF YOU REMOVE THE UPPERPLENUM(UPPER INTAKE USUALLY BLACK PLASTIC HOUSING ON ENGINE)YOU CANCLEAN THE PORTS OUT WITH A SMALL PICK-THIS PROBLEM WILL CAUSE AMISSFIRE CODE EVERYTIME Answer I have a 98 Windstar and about two years ago the check engine lightturned on. I asked my neighbor, who is a mechanic for a local Forddealership, about it. He said that a Ford mechanic is the only onewho can "turn it off". They have a computer that they plug into theengine and tells you what is wrong. Then they are the only ones whehave a code that turns the light off. In my case it was cracked 3"long rubber air tube. We had the same problem with our '96 Windstar. #4 & 5 cylinderscame up in the computer as being bad. New plugs & wires helped#4, but #5 was still showing bad. Turns out, even though theinjector code did not show up, 2 of the injectors were bad. Thistook care of the light problem. We did NOT have to go to a Forddealer in order to get the light to go out... your regular mechanicshould have diagnotic tools and be able to "flush" your computer'smemory of the bad codes. Answer I have the same problem on my 96 windstar with > 100000 miles.This is apparently a common problem with high mileage windstars(3.8L) and assuming sparks, fuel, injectors, o2 sensors etc. checkout OK, it is caused by the build up of carbon in the EGR orificesin the lower intake manifold. The problem can be fixed by removingthe upper intake manifold and cleaning the carbon deposits from theEGR orifices. The misfire happens because the orifices on ports2,3,4,5,6 get blocked first (#1 furthest from EGR valve) thereforewhen the EGR valve opens, most of the recirculated exhaust gases goto #1 cylinder weakening the mixture excessively resulting inmisfiring. -- I had the same problem on my 96 Windstar @ about 100k miles andreceived the same diagnosis of carbon buildup on the intakemanifold. We removed the manifold for thorough cleaning anddiscovered a blown manifold gasket at the #1 cylider. i had the same problem with my van, I took it to the dealer andthey checked it out as being the coil going bad. so far so goodwith it. Answer did you disconnect the neg battery termanl to reset your CPU &if so do you still have the miss it could be a coil or wire Answer I had the same problem on my 1996 Windstar and found that the #2fuel injector was bad Answer The plug, wire or coil could be the problem. Usually if the injector is failing you will get different codes. I just replaced plugs and wires from a 2002 and they were in verybad condition. The van had 90,000 or so miles on it. When thesewere changed it ran like a new van. The back three plugs were just awesome. (sarcastic) That is anotherissue though. Good luck. See "Related Questions" below Answer ( Full Answer )
Code 37 means An open or shorted condition detected in the torque convertor clutch solenoid circuit
I had this problem and it drove me nuts. Replaced coils, plugs. wires, fuel filter etc. Ended up taking truck to a good independent mechanic and he wiped the programing of the computer and started fresh with new programing. Haven't had a problem since. Never felt a misfire to begin with.
How do you fix 1995 Dodge Neon error code 11 This code means no reference signal for distributor during engine crank.?
Code 11 means: Intermittent loss of either camshaft or crankshaft position sensor,/No crank reference signal detected during engine cranking/Timing belt skipped 1 tooth or more from initial learned value. Could be any of the above, need to check with a scanner to check sensor readings.
To fix an engine light code of 133 on a 1996 Ford Bronco with a 351engine, the oxygen sensors need to be replaced. There are twooxygen sensors on this vehicle. One is on the driver's side and theother is on the passenger side of the exhaust or catalyticconverter.
Catalist temp performance poor. Esentially the 02 sensors are reading poor cat performance. It could be the )2 sensors are old and tired but most often itmeans the Catalist needs to be replaced.
Consider: . If you have a code P0171: . Check for, vacuum leak or loose hose at throttle body or MAF sensor. Favuum leaks are common and may present a hissing noise. If you can spray carb cleaner near intake gasket, on vacuum hose, or intake hose someplace where it changes the sound of the eng…ine you have found your leak. Check for an exhaust leak. Exhaust leaks have a very distinctive sound. Check for a misfire. Your car shakes. Check for faulty or damaged MAF sensor: -Runs better with MAF sensor unplugged or: -Banging MAF sensor with your fist whilke engine idling makes a change in sound of engine or: -Remove MAF sensor and look at the wire. If it isn't clean and shiny silver color, it is contaminated. Clean or replace as needed. . Assuming no complimentary code P0171: . Bad oxygen sensor upstream (before cat) bank one. Bank one is the side with cylinder #1. Water or extreme temperatures affecting sensor operation. Remove water or wait for weather to improve or replace sensor. .

P0300 Diagnostic Code - Random Misfire Symptoms. Engine may stumble or miss Engine may be hard to start you may notice no issues Cause Failing spark plugs or spark plug wires Bad coil or coil pack Failing oxygen sensor(s) Bad fuel injector or more than one Stuck exhaust valve Bad catalytic conve…rter EGR valve or valve passage clogging Bad camshaft position sensor Bad PCM or ECM The Fix Best first action is a tune up, newplugs, wires, inspect all hoses and wire connections then reset thecode. If it returns you will need to narrow it down to a system, coilsand coil packs should be tested, catalytic converters for function ( doyou smell rotten eggs?). A misfire that jumps cylinders could indicate alean condition, do you have any other codes along with the 300? thiswill help clue you in to the source, check valve function to make surethey are opening and closing fully. This is probably pone of the mostdifficult codes to troubleshoot, so start with the basics and work yourway into the more expensive options, in many cases a good old tune upsolves the problem, back it up with a fuel system cleaning and see whereyou stand.

What can you do to fix your car from shaking when you accelerate 99 Tracer check engine light blinks no code in computer?
If the light is flashing there is SOME kind of code in the computer. It may be an ABS code, a transmission code or who knows what. Unfortunately you'll need to find out what it means and engine diagnostic scanners don't always tell the whole story.
Normally, the answer a mechanic provides is to replace the distributer, alternator or wiring. It seems that the common thread is the PCM. HAve all other parts tested first.
The engine code P0355 is for a malfunctioning ignition coil. Thiscan be fixed by replacing the coil. It can be purchased at any autoparts store.
More than likely it's your IAC or Idle Air Control motor. It's usually right on your intake cover somewhere, check with your repair manual to find out what it looks like and how to remove it.

Oxygen Sensor. There are actually (4) O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints togeth…er, you went about 6" too far. When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat). Normally it is the upstream sensors (sensor 1) that go first.

Trouble code P0203 means: Injector Circuit / Open - Cylinder 3. I think you need to replace the Injector on cylinder 3. . Remove the air intake snorkle that covers the #3 and #4 injectors. On the bottom of the snorkle you should find a metalic pad. Now, look at the wires that feed the #3 injector.… If the injector is turned to just the right position, the wires can rub on the metalic pad. If it wears enough it will rub through the wire insulation and you will be able to see copper stranded wire as a result. To repair this, place some automotive-type silicone gasket maker (in a tube), covering the bare wire and then allow to dry for 24 hours. Also, turn the injector 45 degrees (either right or left) to move the wires away from the metalic pad. This will effectively lower the wires so that they won't rub. Another thing that could be done is to add a 1/4" spacer under the snorkle bracket on the front locating stud. This will also increase the space between the bottom of the snorkle and the #3 injector wiring harness/connector. If this doesn't fix the problem then it's probably your injector. ( Full Answer )

How do you fix a recurring number 4 cylinder misfire diagnostic code on a lesabre 3.8L engine after changing sparkplugs and wires?
most times it is a bad coil pack there are three ignition coils mounted on top of the ignition module. one coil supplys 2 cylinders with spark. original coils have the cylinder number stamped on the coil so you know what coil feeds #y cylinder. 80 percent its a coil failure 20 percent the module fai…l and signal is interrupted to coil.if you don't want to just change coil.without proof,you can switc coil with another remember to mark the number of the cylinders on the ignition wires before you switch coils as the coils have a firing order that must be followed. when you switch coils and test drive check the coses for misfire again if the miss moves to a different cylinder number the coil is bad. if the number is still four with the coils switched,the ignition module if probably bad, these coils usually tes good when you ohm test them but these coils usually break down under engine load and heat,your coil can pass a ohm test but still be bad. there cheap enough just put new #4 coil in it. p.s you need a 5.5 millimeter socket to remove coils ( Full Answer )
