Check fuel injectors or fuel regulator . could have 1 or multiple going /gone bad. Replace Probably not O2 sensor, when bad they run rich but no stalling.Could be pump, start with easiest and cheapest first. Good Luck!

Have you replaced fuel filter ? Sometimes with time, dirt collects inside fuel tank and clogs the filter which may cause your vehicle to shot off.
Also check for any codes which may be present and causing your problem

1985 cabrio stalls at about 1 hour into my commute


hi,

put in on a vacuum gauge and watch it untill warm up. the gauge should be steady all throughout the idle and when you punch it. sounds like an intermittent vacuuum leak. listen for hissing in the engine comparment. put it on a scanner if it keeps it up. its time for new vacuum lines.

2004 Jeep Wrangler Rubicon stalling out


I've had this problem on vehicles with 70k or more miles on them. Symptoms include rough or uneven idle and dying. OBDII showes no codes.

Bad fuel, vacuum leak, low fuel pressure, carbon build up, inoperable fuel tank ventilation, poor grounding, low voltage, intermittent relay contacts are possibilities.

The simplest and mostly likely problem is:
Carbon build up inside the butterfly. With the engine off, pull the intake off. Use injector cleaner and a shop rag to clean the intake throat where the butterfly is. Use a plastic or wood handle to hold the butterfly open to get both sides cleaned. If this doesn't clear the problem, check for vacuum leaks, loose hoses etc.

Check fuel pressure and replace the fuel filter if it's low.
