Jeep Grand Cherokee
#619 of 1240 Erractic Idling/Engine Stalls
Jan 12, 2010 (11:16 am)
I have a 1995 Jeep Grand Cherokee. 5.2 Litre V-8. 160,000 miles. Engine starts right up but stalls immediately unless gas pedal is held down for a little bit or as long as 5-10 minutes. Sometimes you can drive up to ten miles and it will die anytime you let off the gas pedal whether going 30mph or 70mph. Sometimes you can go several days without this happening at all. Weather or temperature don't seem to matter. Also idles erratically(slow to fast repeatedly). Can anyone help me narrow this down. A lot of sensors could be at fault although no codes or indicators are ever present. Thanks.

Again, not being a mechanic, I have to say that you need to get hooked up to a computer to find out what your sensors are saying. Mine was a $70. sensor (retail) that my mech said he installed at his price $168. It was the MAP sensor. Prior to that I had a parts replacement thing going on that eventually came to more than $500.
Watch out for mechs who don't know what's going on and will replace parts at your expense until they eventually hit on the right one. If you know of a "great" mechanic, and is also honest, make sure he is in your last will and testiment...

I have read this forum exhaustively for an answer and am unable to come to a definitive solution to my problem.
My Jeep starts fine and will run as normal for almost exactly 1/2 mile, then it shuts down and will not re-start...Wait a few hours and this cycle will repeat itself. It will idle all day long.
Good fuel pressure
Recent Throttle Position Sensor (and I removed and cleaned it)
Recent plugs, cap, rotor & wires
Cleaned and tightened all ground connections
What is the most logical diagnostic progression?
Idle Air Control Sensor?
Crankshaft Position Sensor?
Powertrain Control Module?
Something I haven't thought of...?
Any advice is sincerely appreciated....

It looks like I need to jump at one of these solutions and see what eventually works. I'll post the answer when found.
