Hello, I have a 2004 Jeep Grand Cherokee v6 that is giving me some problems. It continues to shut off while driving or stutters when taking off at a light or turning when yielding. This started after the vehicle overheated when the cooling fan went out. Replaced the cooling fan then the next day my Jeep started to turn off on its own and stutter/hesitate. First replaced the crank shaft position sensor because we got a code and it was bad. Problem continued, then replaced the throttle position sensor, it continued, then replaced the fuel pump relay sensor, problem continued. During this time the water pump went out so replaced it. Then replaced the fuel pump, fuel filter and a new battery.....problem of stuttering/hesitation and turning off while driving still continues. It also now doesn't turn sometimes, it cranks but doesn't turn on sometimes. Have taken it to three mechanics, tested it all day, check for loose wires/hoses and still nothing. Dealer said it will be until June when they can take a look at it. Any suggestions? Going to clean the IAC today to see if that does it. Ughhh!! It's a great vehicle and was working perfectly fine before the cooling fan went out and was replaced. Please help!

 

Stop throwing parts at it blindly. Do some diagnostic work, like a compression and leak down test. Are you losing coolant? Did this stuff happen before you overheated?

 

No I was not losing coolant before it overheated. It was driving like a beauty before then.

 

You may have damaged the engine when you overheated it.
