    I would really appreciate any advice here about what I'm about to do. 2014 JKU Sahara still in stock configuration except for aftermarket headlights and taillights. Long story short (I'll put the long story in a separate post), a reputable mechanic after troubleshooting my P0306 code (cylinder...

    Hi all. I am new here. Was searching through other posts but could not find anything pertaining my question so here it goes. Recently bought a 2012 Jeep JKU Sport with the wonderful 3.6L VVT Pentastar engine. Was having issues with the camshaft position sensor on bank 2. Located a signal wire...

    I decided I was going to order a new PCM based on various bits of info and ruling out certain items. Perhaps, not the best idea I ever had, I decided to open up the existing PCM to determine if I could visually identify any damage. From what I had gathered (on the interweb), many times a bad...

    Hello everyone! I've got a Renix 2.5L TBI computer I'm selling. This does not look to be the original, as opening it up it's not filled with the gel that all of the originals seemed to have. In fact, this model lives above the glove box. This is clean and functional, and came with my jeep. I...

    So my buddy has a 2010 Rubicon Unlimited. 3 inch lift, factory gears, 35's... His ECM is heating up at idle and puts it into limp mode. Once the ECM reaches a certain temperature it stops processing the information from the speed sensor. That causes it to go into limp mode and it wont shift...

    Recent misfire on my 05 wrangler. Got the random misfire, cylinder 6 misfire, and x4 O2 sensor codes. Replaced plugs and coil pack, misfire hasn’t come back but the O2 sensor codes are still there and will not go away. Checked the O2 sensors and they’re still good, but there’s no power going to...

    I just bought a used jeep, and have been going through this nightmare recently. I have a 2004 TJ 4.0 liter automatic transmission, it has been driving around in second gear, after about 20-30mph the rpm will go over 2000 and up. A buddy of mine plugged in his reader and found the error code...

    Hello guys, I have a 2000 TJ 4.0 5Spd and would like to update the ecm to a newer one that will display the codes in the odometer when the key is cycled. Can someone advise on what to look for to ensure it all works without a ton of trial and error trips to the junkyard? I have only added a...

    Hello All, I'm trying to troubleshoot my 99 TJ, straight six. The deal: I drove it around town in the AM with DW. Parked it and removed the fenders (swapping them with different ones). Then decided to run to the store. It started fine, and as I was backing out of the driveway, it...

    The struggle is real! Was riding down the road and my 1989 YJ starting missing badly about a mile from home. By the time it got me home it would hardly run and finally just died - inside my shed thank goodness. Now it has no spark coming from the coil. I replaced the coil and condenser...

    Hey guys, just got back from a deployment to a whole host of vehicle issues. My superduty had 2 dead optima red tops. My 2013, currently on jackstands, had 1 dead yellow top. I got the truck taken care of, but now I cant get the jeep to start. The funny thing is, when I got home I found the...

    My 05 wrangler with the 4.0 and 42rle is stuck in limp mode. Over the last eight months I've been dealing with this issue I have replaced every sensor on the jeep, brand new exhaust system including all new cats and cat-back. I originally thought it was a ecm issue so I sent it out to a company...

    I was getting no fuel pump and no check engine light. So I replaced the capacitors in the ECM. Thought that did the trick but I can only get about 1 start and then no check engine light again. I have to let the jeep sit overnight before it will start again. Any help is massively appreciated...

    Hey all, I’m hoping someone with more knowledge than myself might be able to help me solve this. I’ve owned this 2003 Wrangler for a little less than a year and it has ~80,000 miles on it. It has a 4 cylinder manual transmission and is currently stuck in southern Utah, unable to get above 30...
