The two most common causes of this on your vehicle is the crank position sensor and/or the fuel injection unit. It is very common for this fuel injection unit to become clogged internally and cause instances when the vehicle will stall or hesitate. ' If the cleaning solves the problem then it should only be about $80. If for any reason the injection unit needs to be replaced this is usually about $500. As for the crank sensor this can cost about $150-200.

Im looking at a jeep 2002 with 4.7l motor. was there any problems with that year over all?grand cherokee sport.135000 miles.im a women with no knowlegde of buying a vehicle by myself. thank you jody


The 4.7l is an overhead cam V-8 motor. It is plagued with problems involving sludge build up, poor oil circulation, and engine failure due to lack of lubrication. Personally, I would avoid any vehicle with this engine.

2002 Jeep Cherokee with 22,000 miles has check engine light on. What can this be so early in the mileage


Hi:
There are hundreds of things that turn on the check engine light, some are simple, like the gas cap loose, others are more complicated. A good thing to try is to stop by a local auto parts store, such as Auto zone, and most will scan your code for free and tell you what possibly caused the light. This way you can know for sure !

Check the battery. If it starts to fail it will start doing any conceivable thing including failing to start the car. Have the battery checked with a load tester. A simple voltmeter will not give an account of the requirements needed and the ability of the battery to meet those requirements.

Jeep Grand Cherokee Power Loss


a bad cam sensor will cause vehicle to shut off while driving, and cause a hard time starting. but this usually sets a trouble code p0340. scan vehicle to see if any codes come up. after it is fixed, erase codes with a obd2 scanner. if you do not have one, you can go to any auto parts store and they will erase codes for free.

Any waranties left? Is oil full? Any noises from engine? Did you put a mechanical gauge on it and check "real" oil pressure? (I would not drive it 'till I was sure about actual oil pressure!!)
