Sorry, No check engine lights, plugs and wires have been replaced. Dad's mechanic told him the coil packs were ok. The engine does not backfire, just runs really rough. Again, this only happens when it is in gear. I had the same problem with a 97 Bonneville, except the problem was intermitent. Finally after replacing all three coil packs the problem disappeared. I am still suspicious of the coil packs, but I am not a trained mechanic. Thanks for your time.
