Need Help

    I'm driving down Rt 13 today on my way back to work, long story and my jeeps starts to sputter, does this on occasion. Normally there will be a pop comming from under the Jeep and every thing is ok. Also this usually happens when the jeep is just started from sitting after a day.


    Well to get on with it the sputter does not stop, the jeep tries to stall and there all kinds of pops comming from under the Jeep, I think they are backfires but cant be sure. Can anyone tell me what they think is the problem, my thought is maybe fuel filter :shrug:

    mines been doing that in the mornings when i start it to go to work it idles weird and then revs a little high then its normal......sorry i cant help but im wondering about this too

    How many miles are on it? Last time you had a tune-up? Spark Plugs, Wires, cap&rotor, injector flush? I think the fuel filter on your jeep may be in the tank with the pump and is generally not serviced. There was a TSB issued for extended crank times on some Jeeps. There was a problem with an O-ring on the fuel pump module that went bad. The fix was to replace the o-ring. The kit was about 16 bucks. I would look at the simple stuff first, the tune-up stuff, then maybe a fuel pressure test to see if your maintaining your fuel pressure, if youve got a clogged or leaking injector, leaking pressure regulator, etc.

    Mine used to only do that in the morning as well but it's getting worse. Comforting to know that I'm not the only one though.

    Check out the plug wires
    the #1 plug will ground out on the AC bracket


    That was one problem I had with my 2.5 and it caused stuttering badly.

    i just had new wires put on and a new rotor and cap so i guess the plugs are the next think to check. could the new k&n be a cause for some of the problem? it is a cone style and i did it my self but the fitting is air tight could it be tomuch air gettting to the engine? how can you clean the fuel filter on the tj's i think mine is in need if a cleaning.

    The plugs are new, I'll try some new wires, and everything else.


    Omaha mine has done this often in the morning ever since I got it, and for a little while it was stock.
