Re: Lopey idle on an 02' Overland / 4.7HO
I had some of the same issues with 04 JGC limited Quadra. Rev's up almost 1800 rpm at a start, tranny downshifting then up shifting, cruise at 70mph and the RPM's would raise 300rpm then drop back. It was horrible to drive, didn't know what to do as no check engine code. I watched this forum and BINGO! replaced the TPS and start up is normal, idle is great, shifting is like a new tranny, cruise if perfect 70mph and 2000 rpm and it stays level. FIXED!! Thanks so much for all of the post and helping me fix my JGC.
