    sjuts down at 2000 RPM

  • robert626 Jun 19, 2009

    No it was not but I checked it with a volt/ohm meter and the readings were right what the book stated they should have been

  • robert626 Jun 19, 2009

    Oops, yes changed fuel filter and fuel pump, and air cleaner

  • robert626 Jun 24, 2009

    Ok---Thanks for all the tips and I think it may be fixed now. It has made it three days at extended runs over 2,000 rpms I replaced the ignition coil and I mounted it off of the engine this time. It was the only thing left in the loop. Time will tell.

I would try the crankshaft sensor. About the only thing left in the electrical department. These are known to heat up and fail. Also could be a weak fuel pump, but not as likely as you say it restarts immediately. You should have the fuel pressure checked before replacing it, as it's pretty expensive. ~ $175. I had one that would die intermittently, then it wouldn't restart until you got under the back and kicked the gas tank.

I have a 2004 Jeep Grand Cherokee Laredo 4x4 with the 4.0L. It has approximately 150k miles on it. I started the Jeep with 1/4 tank of fuel in it and it started rough and acted like it was going to die....


long post.
ill reduce it for you.
misfires. (is RPM below 700 then misfire can be normal) for idle speed controls dead.
ISC the isc controls speed, of idle,.
mine stuck like zillion times, in 400k miles. endless.sticking
mine was a tiny gutless stepper motor drive ISC valve.
the cone valve is side gets nasty and sticks (
(PCV gases caused as seen on all engines)
i clean it.
the proof is the easy press of right foot easy raises idle back to 700rpm and engine stops misfiring.
ever get a tuneup this decade or running spark parts 500,0000 miles
for the new world record.?


now the tricky part of ISC, , fully explained in the SM serv. man.
the PCM learns its behaviors.
it learns all hot start settings and cold
so when you key on, it goes to the correct HISTORICAL spot.
if it can move there(sticks) engine car race.
or run too slow,
cold start would be worse, as hot isc is more closed
so if sticks there closed, the next cold start will be horrid
some newer manuals telly you to add 5% throttle if car is hard starting this is so common.

clean it. end story.

1994 Grand Cherokee, 5.2 V8 shuts off when hot. Cool for an hour or 2, starts up ok for a half hour or so, then dies again. No trouble codes except 12 and 55; I pulled fuses to check them, hence the code...


Your engine computer is bad. It's a good thing that you mentioned about the check engine light dying also, as this is a classic sign of a bad ecm. I have repaired more than one of these Jeep computers, replacing the three power capacitors located inside the computer, and they have worked for years afterwards. If you don't have the skills or knowledge to repair the ecm, get yourself a rebuilt ecm unit and swap it out.

Need to know the plugwire placement in 1994 Jeep Cherokee


That vehicle came with three different engine options for that year, there was a 2.5 liter inline 4 cylinder engine, a 4.0 liter inline 6 cylinder engine, or a 5.2 liter V-8 engine. Here are the firing order diagrams for all three engines and one of them should help you to solve your problem.


2.5 liter.

Jeep stalls


try doing the procedure below, should cure the problem.
Here is the common cause of surges, 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, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Battery trouble??????


SOMETIMES YOU JUST NEED TO START THE CAR AND GIVE IT SOME GAS. IDLE IT UP TO ABOUT 2500 RPMS FOR A MIN OR TWO AND THEN TRY RESTARTING.
