Hey i have a 1997 Mercedes E320 and the check engine electronics is appearing and it runs about 40 mph and it feels like it pulls back like a standard car what could be the problem?

Seems to me like you have symptoms of a bad Engine Control Unit, The ECU directly ties to your emmission system, which controls acceleration, have you tried erasing the fault code with an OBD 2 scanner, pretty simple you could buy this scanner from Ebay for about $80.00. just plug it above your pedals, message gone and will also give you a code, if your ECU is bad, then you will have to replace the ecu, Get the part # from the dealer of the ECU, buy it from Ebay for about $200.00 replace it, erase message again with scanner. save a bunch of $ Seems to me like you have symptoms of a bad Engine Control Unit, The ECU directly ties to your emmission system, which controls acceleration, have you tried erasing the fault code with an OBD 2 scanner, pretty simple you could buy this scanner from Ebay for about $80.00. just plug it above your pedals, message gone and will also give you a code, if your ECU is bad, then you will have to replace the ecu, Get the part # from the dealer of the ECU, buy it from Ebay for about $200.00 replace it, erase message again with scanner. save a bunch of $

How do you open a doc file in command promped?

i think this function is not available in ms dos . you can access the .txt files through dos and you can also able to print them through dos. if you are going to just open doc file than simply open dos drag and drop that file to ms- dos window after that hit enter and it will open.

What is the importance of math in the electronics field?

One look at electronic and electrical textbooks yields the answer. There are many different areas of electronics, involving needing mathematical knowledge about electricity/magnetism, power/heat dissipation, how circuit components behave, system response to excitation, and much more. I will provide at least one example link to give a flavor:

What are the types of test used to verify the correct functioning of electronic equipment?

1. To test the functionality of a piece of electronic equipment, calibration tests can be performed in various ways. For example in equipment with variable outputs that are not calibrated (some power supplies), a test using a multimeter or oscilloscope (obviously both being within calibration) can be performed to compare the output voltage to the measured voltage and thus adjust the variable outputs to the correct value required. For pieces of equipment that do require calibration; if the equipment comes out of calibration before the re-calibration date, calibration should be performed or organised before use.

How do you 3 way call?

1. Call one of the people you want to three way call with. 2. While talking to that person, press talk (send, or green button) then dial the other person's number you want to three way call with then press talk again. This should work...

Are xlr cables stereo?

3 pin XLR's are mono. 5 pin XLR's are special connectors usually used in stereo microphones, but usually split on the other end to two mono XLR's.

How often should smoke detector batteries be changed?

When the smoke detector first starts signaling low battery with short widely spaced high pitched chirps, or if when you press the test button the alarm does not trigger.

After replacing the batteries, press the test button. If the alarm does not trigger with fresh batteries, replace the smoke detector.

What is boost coil?

Its function is to increase current. If this coil gets damaged then it has to be changed.

Does capacitor banks produce harmonics?

No, capacitor banks reduce harmonics. They act like a low pass filter. They also raise voltage by compensating for inductance and bringing the power factor back closer to 1.

Capacitor banks in the power system can cause transients when randomly closed - many utilities use zero voltage closing equipment, or inductors to counteract this short time harmonic problem.

What answer of if operating system denied access to the specific files?

if any operating system denied the access to any file it means that file is protected by any other person or may be system file which is very necessary for operation.

and also a matter can be that , a person locked that file with a computer program and that program will ask a password for opening.

Is there a way to produce an audible tone at 1.605 MHz to be listened to through earphones or is it too high of a frequency?

There is no way to produce sound of this frequency that you will be able to hear. Human ears have a high frequency limit of approx. 20,000 Hz. This decreases with age to around 16,000 for many people. You propose to create a air pressure wave of 1,605,000 Hz. There is no earphone on earth capable of creating that pressure wave, nor any ear capable of listening to it. Ultrasonic frequencies in this range are used for medical diagnostics and industrial design and testing.

Electronics used during World War 2?

Electronics played an important role in WW2 and literally thousands of books and articles treat the subject in depth. Briefly stated although the first electronic computer was not made during WW2 it followed less than 16 months after VJ day and was a direct descendent of the hybrid electro-mechanical computers used for code breaking (ie The Bronze Goddess of the Ultra cryptographers) and ballistic work. Other notable feats of electronic wizardry include the Proximity Fuze (Johns Hopkins Applied Physics laboratory Silver Spring MD), Microwave megatron Radar (Britain and MIT) "Huff Duff" beam detection (Britain) Television aided bomb guidance (Germany) Electronic beam navigation and bombing sighting (Germany) radio telemetry guidance (Germany) ASDIC and SONAR (Britain) not to mention all the electronics involved in the Manhattan project (nuclear weapons). These are just a few of thousands of examples of electronics applications in the Second World War.

Will Team Fortress 2 work on a HP computer?

The kind of computer you have doesn't matter. What matters is how powerful the components inside the computer are. Here are the system requirements:

PC System Requirements

Minimum: 1.7 GHz Processor, 512MB RAM, DirectX® 8.1 level Graphics Card (Requires support for SSE), Windows® Vista/XP/2000, Mouse, Keyboard, Internet Connection

Recommended: Pentium 4 processor (3.0GHz, or better), 1GB RAM, DirectX® 9 level Graphics Card, Windows® Vista/XP/2000, Mouse, Keyboard, Internet Connection


Mac System Requirements

I bumped my WD removable hard drive now I can't access it is there a way to restore the files in it?

Chances are you did more than just "bump it". Newer HDD's are very good with dealing with Motion and are reactive.

That said, if you hear clicking or scratching, the hard disks are probably getting ruined and it would be very expensive to get information off of the disks. (Companies that do recovery, transfer the platters to another enclosure to extract data, which requires a clean-room environment) There are many places that do it, but it won't be cheap:

How can you easaly reattach i wire to something?

If you can solder, then soldering the wire back where it belongs is probably the best long term solution. If you don;t know how to solder or don't feel comfortable soldering the particular piece of equipment, a technique that i have used in the past is to place a small ammount of aluminum foil on the terminal you want the wire to attach to, and then fold the foil over the wire, and tape down the whole affair very well with electrical tape or duct tape. It is not a permanent solution, and you have to be extremely careful to only let the foil touch the wire and the terminal you want to connect together, other wise you could cause a short. If you are careful though, i have been able to make this setup work well enough to keep things running until you can fix the problem properly.

What is the name of excel files?

Hey,

I don't know if this is what you mean or not but, if you mean, 'what is the 'code' at the end of the files', then I think it is: .exl

Hope this helps JJ x
