Sometimes the engine runs great, then it starts missing for no reason and eventually dies. It will start later on if I let it sit long enough. Changed the ignition coil because it was cracked but this did not help. My mechanic says it is ECU and he can't repair. The dealer says it is not the ECU and that I have "bad gas". Gas has been replaced an I still have problems. Anyone have any ideas?

your fuel filter may be getting clogged. The fuel filter is part of the fuel pump!!! So, yes, u need to remove the tank & take out the pump. the filter is actually a screen on the bottom of pump & can cost $15-25. Tank removal is easy if you do not have too much gas in it. Hope this helps

Hey, I have a 1997 Jeep Grand Cherokee Laredo, and it seems to have just died. Went out of a cold morning to start it, and the battery wouldn't seem to push the starter motor. I checked the battery, it was low, put it on a trickle charge for a few hours till I got green. Reconnected the battery and tried to start again. Again, nothing. No sound, no movement, nothing. I've not owned a vehicle this new before, and understand it might have a bad control module. All I know is that it is not activating the starter.

I have a 94' Jeep Grand Cherokee limited w/6cyl. My battery was very old. So replaced with new one. Jeep still has a steady discharge 11.5-11v. Does not charge when jeep is reving nor does it drop in idle. Voltage drops when lights are on. Before I replace everything I hope to get a little help. Thank you.

i have a 1997 Jeep Cherokee, and it keeps stalling. right now im back in my office waiting to be picked up cause i just brought it back to the shop for the 5th time. They cant seem to find the problem. it just stalls out of no where and at all differnt times. Sometimes while driving, sometimes while at a stop and sometimes it runs great. i have had a full tune up, new crank censor, new muffler and a whole bunch of other little odds and ends tuned up. does anyone know what the problem might be?? i would appreciate it. im going broke!!

I learned the hard way that Jeep Grand Cherokees require Champion spark plugs. sounds rediculous. shouldn't make a difference but I used Bosch plugs and my Jeep started missing badly. I put the Champion plugs in and it ran great.
