This could be as easy as a tune up. Check the inside of the throttle body for dirt build up. Spray throttle body cleaner into the throttle body and you'll see alot of black dirt come out of it. Continue spraying until the cleaner looks fairly clean. What could be happening is the dirt is clogging the small gap that has to be at the throttle plate when the plate is closed. The small gap is to allow air to enter the engine to keep it running at idle.

My 03 e500 shut down when my heater is on at a stop light


every time you put the heat on the engine stalls. but the car starts right up? all I can think of would be to disconnect the a/c compressor connection, may be is frozen or over charged, if unpluged the engine does not stall, have someone look at the compresor.

Since you can drive about 30 min before problems show up it would probably be bad coils. The other ones listed would not give you such a lengthy grace period and the coils are the only ones prone to overheating when weak. Best guess.

My 1989 Acura engine light stay on all the time. Car is running pretty good except once in awhile it will stall when I am at a stop light. It then starts right up but it will happen again later.


Hello Scott,

Thanks So Much, for contacting me. I believe,, based on your symptoms, that you have a bad 02 sensor relating to your emissions, which is happening by your Cadillac convertor. I would have auto zone or place like that in your home town confirm this. They can check with there hand help diagnostic computer to check to make sure it is the one i feel is out. Once they have, it will cost about 80 bucks and problem solved. Engine light will be off and of course car will not stall at stop lights anymore. Based on the year of car, i think that is your problem. If you feel that this makes sense and you can trust I am accurate on the problem, please rate my solution as well as some kind words always appreciated. If you need additional questions, feel free to contact me anytime. I also give a 100% money back guarantee on my solution. Thanks So Much, Mike

Car won't start when turned over unless the pedal is feathered


A sticky fuel pressure regulator could cause line pressure drop on hot start. I'd try a good fuel system cleaner like BG's 44K before replacing any part$ tho.

Every 10 days to 2 weeks the engine starts to shudder (as if it's going to stall) followed by the flashing check engine light. Stopping the car and reseating the gas cap seems to correct the shuddering. At...


Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. What did the dealership tell you???? NO trouble Codes?

While in park truck studders and stop running. then starts up again.


u may have a problem with the TCC (Torque Converter clutch) control solenoid, this causes the torque converter clutch to stay locked up and the engine will shudder and stall, I am 99% sure that is the problem.

98 eclipse Engine stall but stars


Sounds like your IAC (idle air control) motor needs to be replaced. If you are driving on the Interstate/freeway/highway for a bit and then get off, the car dies when your coming to a stop right?
