Starts but will not stay running

After engine fully waked up car will buck intermittantly. It has also developed a habit of the engine reducing to a low growl with no rpm loss but some power loss. Pumping accelerator will at this time clear up both items. At idle when it shuts down the first indication is heavy steering no roughness or anything prior to the stall. Within the last week the fuel pump assembly, fuel pump relay and crankshaft position sensor. In the last 90 days the PCM was flashed for a transmission hard downshift which has since returned. There are no codes to be retrieved and the CEL does not flash or come on. Fuel mileage has not appreciably dropped off. Starting first start of the day is normal. After a stall to get a restart you have to cycle ignition to off then start and it starts normally with no cooling period. Problems are significantly worse during the day with higher outside temperatures. I come to work in the dark and the problems are there but not too bad. This car is VIN Code X. I have only had this car for 12,000 miles or so. I do not have any previous maintenance history. I am thinking maybe an ignition problem but it does not miss. Any Help will be greatly appreciated. Thank you for your time Doug Summers

My apologies the fuel pump was replaced. I will put a vacuum gauge on it. It had a new catalytic converter put on it app 87,000 miles. What is the "asd" relay? I will report vacuum reading as soon as I get it. Thank You

My car stalls at idle. Never when driving. I already took it to the shop several times with no luck on fixing it. Here is a list of what was done to the car.

1. Replace oxygen sensor
2. Clean throttle body (2x)
3. Major tune up
4. Major fuel system and air-intake cleaning.

What else could be causing this problem?

Same with my stratus 1996 125k miles I will replace the IAC sensor, next the TPS, and then the EGR valve one at a time there are no engine lights coming on hope it works, Ciao Muldoon

Ok so it dies sometimes at idle but it always sputters. Never have any issues just driving normally. If you turn the a/c on it gets worse. Its not showing any codes. I already cleaned the throttle body and IAC motor. It did have a stored code p0440, I cleared it and it never came back. I was wonderig what could possibly be the problem?

I dont think it has one

Yeah I stand corrected. It doesnt have an EGR vlave. Its a 4dr.

I would test your spark plug boots. I had this exact problem with my '04 stratus, down to the A/C making it worse and all. The problem was one of the springs in one of my coils was not contacting both the coil and the plug (as it was not holding tension due to being old and subjected to constant heat). You should be able to see this by visual inspection and by feeling the spring contacting the spark plug when it is pushed down into place. A $10 spark plug boot fixed this problem for me. The A/C is robbing the engine of power (as always) and when you are right on the brink of the necessary power this little bit of power robbed can cause the car to sputter worse or even die. I have not had this problem for over a year now since replacing the boot.

I have a 97 dodge stratus, 2.4, auto, have replaced the MAF sensor, both oxygen sensors, idle, air flow sensor, fuel filter, before replacing these; it ran as if the auto choke was stuck, now it seems to starve for fuel, only at idle, or when letting off the accelerator? Don't know what else to replace? Where is the fuel regulator? Could this be it? Or the injectors?

I just got a 93 jeep grand cherokee, 4x4 4.0 straight 6 with 162,000 and have been having major problems with the security system the kill engine came on and cannot reset the alarm I tried unlocking everydoor including the gate I spliced the alarm wire (purple and yellow) and grounded it out which deactivated the alarm took out the vtss module and still will not turn over I tested the spark none fuel pump good but can only get it running of the relay about all I can think of right now any suggestions?

Hey this sounds great! But how do this little ol' country girl find and disconnect the security module. I too am at my wits end over this alarm system that only seems to be in place to keep its' owner from driving it. I have done every thing that I'm told to do but when it comes to disconnecting the system I told that I can get in to the jeep dealer Oct 20. I am a travling nurse and I have to be able to get to work. Could some one please help me? I have a fax number that can used so the info will not be on the internet. Please help! Even telling me where this purple and yellow wire is would be more than I am getting.

Thanks in advance

Hi, I have a 92 cherokee and my security system won"t allow mine to start. Where is the security module located at?
