Is there an easy way to tell if mine is aftermarket?
I am having the same issues. Mine jumps around like it has jumped time then dies. It keeps blowing a P0113 code. So I replaced the IAT sensor still seconds after cranking engine light comes right back on. I replaced the 02 sensors and the air filter still having this issue. Help!!!I have been chasing a rough idle issue for the past couple of months and it is killing me! I have researched this issue and have exhausted all of the threads and can't really get to a solution that doesn't require deep mechanical knowledge or a relatively large amount of money.
I have thrown the usual "easy" solutions at it - new plugs, cleaned IAC and throttle body, run fuel system cleaner through it - but to no avail.
Jeep isn't throwing any codes. Here's what's going on.
Symptom #1: Will idle roughly at a standstill. Barely perceptible but definitely there. Intermittently worse some times than others. Could just learn to live with this except for Symptom #2. See below.
Symptom #2: This is what is weird. After backing the Jeep into a parking spot or my garage, it really bogs down and threatens to quit. Sounds horrible and can't be good for it. After about 15 - 20 seconds of sounding like it's struggling to keep running, it goes back to idling *almost* normally much like it does in symptom #1. By the way, the extent of the struggling varies and I can't correlate it to any specific conditions (heat, length of time running the Jeep before reversing it, etc.)
I will say that these issues don't seem to exist until after the engine warms up.
I have had 3 separate mechanics look at this and they agree they can feel it but can't get to the source of it without it getting expensive. One guy mentioned the O2 sensors which I will tackle next but I wanted to throw this out there to the community in case anyone has had a similar issue, especially if it relates to REVERSING the Jeep.
Help!
Thanks.

Wow, sounds like you've found yourself a reputable mechanic, those are hard to find! Most of them would never charge you less when they knew they could charge you more, so clearly these guys are honest.
I also know for a FACT that if you are running an aftermarket replacement OPDA (as most of us are), the aftermarket sensors that come on them are notorious for not working properly with our TJs. For that reason, most people buy the aftermarket OPDA, but they replace the CPS sensor on it with the OE Mopar CPS sensor.
I'm actually betting that right there is a huge contributor to the issue. Hell, had I known you had an aftermarket OPDA that would have been the first thing I suggested was replacing the CPS sensor with an OE unit.
Moral of the story here is ALWAYS use OE Mopar sensors on TJs. They simply do not like aftermarket ones.
