    Hmm, check the connections around the coil packs. Other than that I cant think of anything.

        my engine sometimes goes into high revs sometimes when i am driving. I noticed mainly when i am in relatively high gear for my speed. when i hit the has it kinda revs up for a second or two (or three) and then stabilize itself. Any Ideas. Thanx

          Mine does the same thing, but mine will from redlining to zeroing out when I'm driving at a constant RPM. Mine actually seems to get better by wiggling the white tach wire where it goes into the PCM. I'm wondering if something got on that connector? Where do the tach wires go next after they come out of the PCM?
