a buddy of mine jsut bought a car about 4 months back and it has been misfiring and backfiring he swapped out 3 new opti's/plugs and wires and finally took it to a mechanic who plugged in the computer and said some one had tried to do a custom tune job on it the mechanic quoted him 900.00 for new computer and distributor.
