SOURCE: Fuel Problem

fuel pressure regulator? This diverts excess pressure from the rail back to the tank. When they wear out they usually stay stuck open thus diverting all pressure back to the tank. Pressure tests do not reveal this as pressure is checked before the rail not in it. I do believe you have a bad fuel regulator. They are 75US ouch.

SOURCE: runs when cold, stalls when hot

Have you tried changing your fuel filter. Not saying that is what it is but when you first start your truck it runs good and the longer it runs the more your fuel pressure drops. It is possible that the longer it runs the more trash the filter is picking up and begins to stall but when you turn the truck off the sediment in the filter settles allowing the truck to restart.

Have you changed your oil? Rotella 15W-40. These engines really don't like old oil. It becomes too thick for the injection pump to work correctly. Another possibility is a bad cam sensor on the front of the motor. Most engines call this the crank sensor but on this engine you have to look it up as a cam sensor.

94 jeep grand cherokee. starts,idle. throw warmup. as soon as I touch the excellerator let up the rpm drop & engine stalls.


Most low idle speed problems on these engines are due to a faulty idle air control valve but since you state the idle will go up and return to idle then i would say it is working properly i think you have a throttle body coking problem ( dirt and grit accumulates around the butterfly valve in the throttlebody ) to fix this simply remove the fresh air hose from the throttlebody and open the throttle all the way up use a clen rag and wipe clean you may use a solvent such as B12 on the rag but dont use too much 1_4_2013_4_54_06_am.jpg

1996 mercedes c280 dies when put in drive


Engine stalls or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

97 dodge caravan start and stall in morning, if warm up 5-10 minutes then no driving problem. if warm up not enough the van will lose idling and stall at stop sign or when my foot is leaving the gas pedal....


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.

I am haveing trouble with my 1996 Mazda B2300, When I start my truck after its been sitting for any length of timeI have to rev the engine to get it started, I have to continue reving until engine is warm...


Replace the temperature sending unit/sensor. This sensor tells the computer to put the engine into cold start mode and it then sets idle a bit higher and puts a bit more fuel into the engine to keep it running without having to touch the throttle. Once it's warm, sensor tells computer to go to normal run mode and it's done. No problem.

4 cyl Engine starts and idles ok...give it throttle and it dies


I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?
