2000 Jeep Cherokee intermittent engine cut-out

problem was solved by replacing the crank angle sensor

I have many of the problems that everyone else has posted. I couldn't pass smog and when I went to mechanic, they told me it was my IAC Motor. Paid $200 and replaced that and still kept tripping "check engine" light. Took it to Jeep Dealership and they told me my PCM was bad. Paid $800 to replace that, and had no problem passing smog. Weeks later, we began to experience the intermittent stalling. I replaced crankshaft sensor, and had no luck. Called Jeep Dealership and they told me that if the PCM was bad, it would throw a check engine light.... I am taking it back to them and having them troubleshoot the PCM. Never had stall problem until they replaced PCM.

ill let you in on a secret from jeep the dealers shop wont even have an i deal about and i dont know why guess its a money thing but if your stalling out and youve replace everything under the sun like your plugs coil crank sensor and cam sensor and that dont work it could be a fuel filter or a fuel injector which all of that you can have checked with a scan tool or you can turn your key on and off 3 times and where your mileage is will give you a code then you can go to the obd-2 trouble codes site and get the results if it is the code 340 which is what it sound like tou could have one of three things you have a bad sensor bad coil pack or the thing the dealer ship or mechanics cant find because most dont know no more than they read or they trouble shoot buy cahnging parts around. with that being said try replacing your oil pump drive unit most mechanics cant even find it but it the thing that run the circuit of info in the sensors listed above its about $280.00 for the part you cant buy it from auto zone or advance auto its a dealer part they might have it in stock if mot it will have to ordered if you know anything about vehichles you can change it or have some one do it for you it is located nuder your camshaft position sensor it should have one or two bolts and a gasket when you replace it it has to go in exactly the way it came out hope this helps plrase pass this information along to the next person with the same problem thank you

Replace your CPS Crankshaft position sensor... Fixed my stalling instantly!!!!

My 2007 grand cherokee would idle or stall mostly when i was moving slow in traffic or at a fast food drive thru on hot days so i put a bag of ice under my hood directly on the computer and so far as long as i keep ice on the computer my jeep runs smooth its only been a couple days so maybe its a coincidence , but in a couple weeks i will repost if there are any changes. If it continues to work i place a small igloo cooler over the computer and run a air duct threw the firewall from my a/c duct from the cab to resolve the problem unless anybody else has another angle on this or idea please let me know.
