SOURCE: 1996 Dodge Stratus stalls when starting

I had this problem with my 99 Durango and went to AutoBeef.com to discover this was a major problem with 98 & 99 Durangos. The fix was easy -- PCM "brain" was exchanged with a refurbished PCM "brain" from an online PCM company in Florida. You can google as I can't remember name of company. I called them and they said - Yep this is the fix -- the guys told me 3 screws all I had gone to several mechanics and dealers -- none could figure it out. I was so grateful that someone gave me the clue I needed.

SOURCE: engine idles and starts ok but stalls out whenn u give it throttle

If the fuel filter does not work, it may be the AIR CONTROL VALVE BOARD which is part of the electronic fuel ignition. I am going through this right now, and found that the "new" ones cost $600 and the used ones are $200, but when you get a used one, you take your chances, so ask for a money back guarantee from the mechanic, or their pledge to put in another one at no additional charge if the first one you get is a bad one the first time, because they are all 20 years old now...

My 2005 Ford Focus won't stay running unless my foot is on the gas. It starts just fine & the check engine light is NOT on. What could be causing this?


It is likely that the engine management system has lost its base line calibration. If the battery is weak and during the crank to start the voltage dipped low enough the Engine Control Module lost its calibration. If the pedal is depressed during the crank the TPS (Throttle position sensor) will lose the idle position for the throttle. The hunting and surging and resultant stalling is the ECM seeking out the limits and re-establishing the throttle idle plate location.

If battery is OK than running the car allowing the calibration of the vehicle to reestablish itself will correct the problem. My experience is that this happens if the gas pedal is depressed during crank with a very very low battery voltage. Always the best way is to not touch the pedal during any cranking starting procedure. Or after a battery replacement.

To accelerate the calibration process attempt to run the car ingear tring not to allow the car to stall. After afew munites the car will have reestablished its normal running calibration and you will be allset.

Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

You did not mention the throttle body or the idle air control valve.
The computer controls idle speed by how much air is allowed to enter the intake manifold thru the throttle body.
If the idle air control valve is faulty, or there is a vac leak, or the throttle body is dirty, the computer can not keep the idle speed at the factory setting.

2003 chevy malibu, takes awhile to turn over and start, idle shoots up and down when started, also it stalls when i take turns


How long since a tune-up? Any applicable trouble codes? With extended crank, you can try cycling the key, on and off, a few times before you crank it. If that helps, have to check fuel system. Use a gage and check proper fuel pressure.
Check and clean the idle air system, see if it helps?

The choke function is not working on a cold engine.
1 clean throttle body and IAC motor air pathways.
2. Check for engine codes, you are looking for a code that relatws to the wngine temperature sensor.

Dies when gas pedal is pressed


This engine has automatic idle speed control, the computer controls a "air bypass" valve on the side of the throttle body where the air intake hose from the air cleaner is connected, the valve and the throttle butterfly get "sludged" up and this causes all kinds of idle problems and off idle stall, see full list below and fix for the problems

Here is the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.

To correct this problem Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional.

Car goes great for awhile and then engine stalls when stopping , and is hard starting unless you leave key on for awhile to let fuel pump catch up.


This is not the fuel pump, this is an idle air control issue. Either the idle air control valve is gummed up or the throttle body interior is filthy or both, the fix is very cheap. Disconnect the air ducting between the air filter cleaner and the throttle body. Using WD40 spray and a cloth clean the throttle interior and throttle plate until like new. Pivot the throttle plate by applying pressure with your fingers and clean in as far as you can behind the throttle plate. Remove the idle air control (IAC) valve from the throttle body and clean the associated passageways and pintle valve. Make sure the electrical connectors to the IAC is clean and reassemble everything. You should notice an immediate improvement to engine performance from start up and no more engine stalls.

This happened to me recently on my 2004 Grand Cherokee. It stalled out three times in a month. No one came up with any codes except that my throttle sensor needed to be replaced ($80). After it was replaced, it stalled two more times, but this time the check engine light never came back on. My local Jeep mechanic looked it over for around six hours and could not find anything. However, my amps on my battery was half of what it should be. He stated that the computer may not have enough juice to control the throttle idle that activates when the vehicle is in low idle speeds. He also stated that once you remove the old battery to touch the battery cable terminals together (you can use a wrench if terminals won't touch) for around ten seconds. This is supposed to drain any remaning juice from the jeep and is supposed to reset the idle memory and computer for the vehicle. After replacing the battery, crank the Jeep up and let it run for at least five minutes without ever touching the gas pedal. Leave it to idle and I repeat, do not touch the gas during this time. The mechanic stated that letting the vehicle run for at least five minutes without touching the gas pedal will set the computer for the Jeep to run efficiently with the new battery and will also set the idle memory for the jeep. I did so and you could actually see the RPM's going up and down until the Jeep found an efficient idle setting. Try that, I know it sounds simple, but I tried every else before this, and it has not stalled out since a couple of weeks ago. I'll write back if it does before the end of next month. Hope this helps.
