    Hello All. I need some help with an intermittent issue that the dealer has been useless for. This is regarding a stock 2016 JKU Rubicon with 41,900 miles. I bought this new in '16 and a week after leaving the dealership, the jeep threw a P0300 code... random cylinder misfire. The dealership did...

    So I just bought a 2003 Jeep Wrangler TJ SE 2.4L 4-cylinder and after a couple days of driving, I noticed the check engine light came on. There are multiple codes that come up during testing, which include 0340, 0123, 0320, 0352, and 1391. It runs fine for the most part. The check engine light...

    I admit that this is a very stupid thing, I accidentally switched to 4L before going to high speed (I originally wanted to switch to 4H). Then when I increased my speed to 80Km / h (50Mi / h), my CEL (that is the yellow light) flashed. I immediately parked the car and found the terrible fact...

    I have a ‘16 Wrangler Blackbear. For the past couple of months the check engine light has been coming on periodically, especially in colder weather. I took it in for a diagnostics check, but it wasn’t pulling any codes. It has been off for several weeks and recently came back on. The only...

    Hey All, Purchased my first 2018 JL on 6/30. On 7/15, tried to start her up and she wouldn't start. Called the dealer to report the error, and they couldn't get an appointment until 8/7. In that three week time span, more issues kept popping up. The start stop wouldn't work, and as soon as the...

    Anyone else have this issue before? We have been having some cold weather in the Northeast this week, and my Check Engine Light went on with a minute of driving, but it drives fine. The Light went on in Late November of this year but my 2010 Unlimited Sport was going in for Service within two...
  16. YJ Technical Discussion
    So I drive a 92 YJ 4.0 5spd, and my check engine light came on (5th gear, accelerating past 50 mph, 1750ish rpm) recently on my way to town. I pulled over, checked all my gauges and popped the hood. Visually and audibly everything seems fine. I killed it and restarted it, and the light went...

    I had this check engine light on for a while. For some time I had the P0431 code without any drivability issues. Earlier today my Jeep began to idle strange and threw a p1604. After turning it off and turning it back on, it began to run normal as it should even with both codes. Drove it all day...

    Bought a 2006 TJ, check engine light on with 6 Speed Control codes, P0582,P0586,P0594,P580,P581,P1593. Trouble is it doesn't have cruise, not sure if it did in the past and the prev owner removed the controls??? Any suggestions on how to get rid of the codes so the engine light will go out? Thanks
