    Jeep TJ possible PCM problems?

    Hey y'all! I have a 98 jeep TJ with a 4.0 motor and manual trans, I brought it to a mechanic to diagnose a idling issue and someway or another the PCM got shorted out by the 02 sensor while they were driving it (so they claim). Sure enough the PCM was bad and the jeep wouldn't start. I replaced...

    Intermittent sputtering with power loss and CEL

    2001 TJ, 4.0, 5-spd, lifted on 33s. Back story: I’m 100% new to jeeps, just bought the thing 4 days ago. Test drive was fine, drive home was fine (60 miles), felt a little sluggish on hills but figured it just doesn’t have the power that my Duramax does. Later, I'm driving straight and flat for...

    TPS?

    Coming home from work the other day, Jeep started "bucking", backfired and shut down. Was able to have someone pull me the rest of the way home. Getting conflicting info from friends that thinks it may be "bad gas" or TPS. With a little more than a half tank, the price to drop and drain is...

    Extremely low idle, poor running

    Anyone ever had this issue? Not a happy camper when being driven for the first time of the day, and once I stop she idle extremely low, in the neighborhood of 350 is my guess. You can feel the steering wheel vibrating as it idles and feels like it runs like crap. TPS is new and IAC has been...

    TPS issues and P0123 code

    Just got back from a long wheeling trip up at Windrock. Drove the Jeep there wheeled 5 days and drove back. The next day I go and start the Jeep and it’s idling really high 1500 rpm and the check engine light comes on. So I go get a scanner and throw it on there P1294 and P0505. So I get a new...

    My cure for a P0123 code

    Let me preface this by saying a couple of weeks ago, my car (Jeep) cover had water in it, as per usual I stuck my arm up to let it drain from the sides. Well this time, the cover came off of the windshield and soaked both me and my steering wheel/ console. I put a hair dryer on it for about five...

    Stripped torx head on TPS

    I’ve been getting my 2003 TJ/X 4.0 back into running condition after years of sitting. in the process of troubleshooting some rough idle and acceleration issues, I was trying to swap out my TPS and stripped the Torx head on one of the bolts. any suggestions on how to remove it now?

    1999 TJ TPS / Throttle Body Question

    I'm replacing my TPS on my throttle body. I took a torch to the screw because they wouldn't come out. And I notice a orangeish liquid coming out around the shaft, it dried hard. Did I just melt a gasket or something or is this some of the loctite?

    Throttle position sensor acting up after replacement: Wiring Issues?

    A few weeks ago I had a crank/no start (and then intermittent stalling) issue that I resolved by replacing the TPS and cleaning up some ground leads. I wasn't quite certain I was out of the woods yet, but it drove fine for a couple of weeks. Today it just stalled twice at intersections around...

    CEL Diagnosis

    WOO! Had the Jeep 5 days and already a CEL. Luckily this page is awesome and I think I sorted it out through older threads but I want to get some outside input on my current situation. First the back ground! I got my car washed about 2 days ago and the genius car wash workers decided to wash...

    Throttle Position Sensor (TPS) going bad?

    This morning, the Muddog, (2002, 4.0, 5 speed, 135000 miles) didn't want to start. Cranked for a while. Nothing. Tried again, got "Check Engine" and "Check Gauges". Turned the key to get the code, P0320. But then it started and I haven't had any more trouble. Will a CPS give you some warning, or...
