Need your help again guys...I just dont get it. Ok my 94 Z28 Auto with 117k is missing under acceleration and you can also feel it miss slightly while cruising. I replaced the opti about a month ago because it was damn near gone. The car does not idle like crap like it used too when the opti was bad. But I did get a coolant spill on it right after I replaced it. DOH! It seems to be alright though. Is there a possibility that the plugs could be causing this. I havent replaced them since I have owned the car. 95k And I have no idea when they were last changed.

Everything else appears to be fine with the car...good oil pressure, temp, etc. It just misses while under acceleration. It seems to be most noticable after the engine warms up. Thanks for helpin guys and gals.

Thanks again, Cory

plugs will hard starting, missfiring, rough idle, just to name a few. replace wires and plugs would be the first thing I would do with those kinda miles...then go from there..
