    Misfire and roughness help

    I'm going to put the two older upstream injectors back in to see if that actually solves the issue being that the reputation of the ones I have are unknown in the Liberty.

    Misfire and roughness help

    I ran some seafoam in it Sunday night, and it's seemed to run a little bit better so far this week. I get a little sputtering when I first start driving, but once I've backed out of my driveway it seems alright. I'm wondering if there could be a fuel delivery issue (fuel filter, clogged...

    I used Denso for the downstream and Delphi for the upstream.

    Misfire and roughness help

    Those are exactly the ones I used, with the factory gap specs. Jeep currently is sitting at about 91k. I don't mind doing coils if it'll solve the issue, I just want to know it is the issue before spending that sort of money. I'll move the number 3 coil and see if the code moves with the coil.

    Misfire and roughness help

    I'll give that a shot tomorrow. Anything else to consider? It's such a random thing that I'm not sure it is the coil. I had codes from both cylinder 3 and 5, but at different times.

    First projects on new Jeep

    Thanks for the advice. I'll probably start saving up for that stuff then. I've still got a couple issues, The roughness I'm experiencing is more prevalent now, and doesn't go away immediately like it did. I'm also now getting a P0137 and a P2314 code. Being that the O2 sensors are all new, I'm...

    First projects on new Jeep

    I've noticed that. If I go with the JBA arms, could I get the lift ones before I'm lifted? I don't want to spend money on something I'll have to replace again when/if I lift. I was planning on going with the serviceable joints. I already hate not having grease fittings. As for coils and shocks...

    First projects on new Jeep

    I've started doing some of that. I'm slowly going through all the fluids. I've done oil and diffs. I've put a new air filter in as well. The Ball Joints all do need replacing, You mentioned the control arms, what am I looking for on those? With the way it rides on rough roads, shocks and...

    First projects on new Jeep

    I'm new to Jeeps and new to the forum. I just bought an '04 KJ with 87,000 miles and after a couple months noticed that I need valve cover gaskets and downstream O2 sensors (engine codes and running roughly). I'm also experiencing a burning smell when I come to a stop. I guess it could be...
