So, I put a CAI and throttle body spacer onto my '09 Rubicon and now the ETC light and ESP come on. Only, they aren't on all the time and sometimes never come on. The engine light also pops on every now and then too...When the ETC comes on the engine gets rough. Simply turning it off and back on takes care of it for a while too.
Thoughts? Gremlins that I've read about with the computer?
Needless to say Day 5 with the new Jeep is a little frustrating...
I didn't have this problem with either of my other Jeeps (XJ and YJ)
If you've only had it 5 days and it is under warranty, that honestly sounds like something that THEY should be addressing. You shouldn't have to troubleshoot all that crap. Maybe a re-flash or see what codes are coming up- if any. Sucks...but yea, the JK is known to have many elec gremlins.
