Anyone one have problems with 3.7 Idle. Seems to be a little ruff like a misfire but throws no codes.

So it's not throwing any codes. Check your IAC (idle air control) in the intake. Just guessing here.

The idle on my 2005 KJ feels a little rough. The rev counter needle is rock-solid where it should be, but you can feel the roughness through the seat. I'll be pulling the IAC to clean it soon, but I'm also wondering if it might be the engine mounts, which the dealership only replaced 4 years ago.
