1997 grand cherokee keeps acting like losing power, backfires and randomly shuts off and now it wont start again...any suggestions??


timing belt may have slipped. usually if the engine starts to back fire and then lose power the timing belt is loose. would check this and replace if it looks suspect. also timing belts should be changed at a certain time or miles witch ever is the grater. average is 4-6 years on a engine that don't do meany miles 2-4 years on a heavy run engine.

What is causing my 1997 Jeep Grand Cherokee Limited Edition to spit, sputter, lose power and backfire?


Sounds like a timing problem, check timing and if off could be timing chain worn out especially if there is excessive miles(200,000 miles or more)

Like many others, I'm having trouble with my '97 Jeep Grand Cherokee with the 4.0 L engine and 4X4. Engine sporadically misfires, especially when coming to a stop. Sometimes dies on idle or startup....


Make sure the ignition coil drive is in proper sync. The sync should be at or close to 0. Also try an engine decarb this works great on 4.0 engines. Also if the misfire is coming for #3 there is a bulliten on installing a heat sheild around the #3 injector because it takeing a lot of heat from the exhaust mainfold that sits right under it.

1997 Grand Cherokee 4.0, ignition shuts down sometimes backfires and keeps going, or dies completely and hopefully starts up.already replaced coil and crank sensor.


The likely answer to your problem is that you have an intermittent disconnect in the ignition system. If power supply to the ignition system drops out, some fuel still goes through and when power returns it ignites in the exhaust resulting in a backfire. I would look for a bad ignition switch, or other loose connection that could me making/breaking contact intermittently.

1997 Jeep Grand Cherokee. Stalls out,engine quits running


since its a 1997 your jeep has EFI, electronic fuel injection. The most probable reason for your troubles would be the injectors or a problem with the computer controling them, not allowing enough gas to be pushed into the cylinder causing stalling or lack of power, also too much gas iin the cylinder can lead to back firing and stalling. This would also explain the reason it takes so long to start back up some times, all the excess gas in the cylinder is flooding the motor and u have to wait till the gas disipates till the engine will turn over.
