My 2000 Intrepid with 2.7L has a miss only when the air conditioner is on and only at an idle or just coming off an idle. At driving speed it's fine. I tested in park and drive. It misses in both, but again only with air on. Anyone have a clue? It has been above 90 for around 50 days here in east Tennessee.
Thanks in advance, Glenn

 

Oh, there is no engine check light, yet.

My 3.5 did that after I accidently left the idle air control valve plug disconnected! I didn't have an engine light (should have one would think) either. I'm not saying you left yours off, but maybe it's bad and you also have no indication of it.
