1997 Jeep Grand Cherokee Question: Car shuts off at random

 

Question

My car shuts off at random. It could be stopped at a red light or at a stop sign or driving 30 mph. I have no idea what is going on. Now i don't want to sound stupid, but I'm a 21 year old girl who knows nothing about cars. So i cant really tell you much other then that it stops when it feels like it. It has never stopped when i was going over like 45mph though if that helps. I hope you can help me before I go to a mechanic and they screw me over for all my money. WHATS WRONG?? HELP??

    There are many different reasons for an engine to stop for no apparent reason. One critical piece of information for your mechanic is to tell him if your 1997 Jeep Grand Cherokee starts right back up or do you need to wait a period of time before the engine restarts. The most common reason for intermittent engine stalling is a faulty crank shaft position sensor. This sensor relays engine speed to the engine computer. When there is no signal form the sensor the engine stalls. There are other items which can also cause this concern so please don't just zero in on the cranks sensor. There may be fault codes stored in the engine computer which could help in diagnosing your stalling condition.

    My jeep stop when ever it wanted. I kept on getting the ignition coil message. My jeep
    strated to backfire.
    It turned out to be the CPU (engine computer).
