Had our 2005 T&C(3.3) in for some extended warrenty work few months back and while there had them change the plugs, something I'd normally due but their access is a real pain. Anyway ever since the engine does a not so little stutter, very random and most apparent when idling, parked, stop light etc. May not happen for quite a few minutes or does it several times in a matter of seconds. Of course i cant replicate it at the dealrs repair shop so they cant/wont do anything. Van now has 70K and wires were changed at 35K. As a side note the ac seems to cycle harder also but they looked and said its normal, maybe I'm just a little more sensitive to every noise now. I'm thinking maybe the a plug wire got damaged , really dont know. Any ideas? Thanx
