Weird issues after wheeling nonstop
Hey guys,
Just got back home from a weekend of wheeling, and have a few issues to hunt down. A large rock ripped the exhaust off where the exhaust spacers go (essentially right behind the headers) and that unsurprisingly threw an O2 sensor code. After patching it up and clearing the code, things got even weirder. Anytime my AC was on, the Jeep would randomly rev itself up. Sometimes it was a little burp (500 rpm rev), and other times it revved itself up to 5k rpm. It would immediately stop as soon as I turned the AC off.
I just tried to replicate the issue, but to no avail. Would being in 4LO for an extended period of time (Friday 5pm-3am Saturday, Saturday 9am-8pm and then 10pm-2am, and Sunday 9am-5pm) potentially cause this phantom gimmick? Aside from food and sleep, the Jeep was on the trails in 4LO.
Anyone else have this problem??

Being in 4Lo would not cause that. Check for any other wires or harnesses that may have been pulled or dislodged. After checking for any other codes, reset the ECM and drive a bit.
