Previous owner changed timing belt.The computer codes are saying everything is fine?Is this a faulty coil or back ignition wires?I did not change the wires cause they looked good.Any help would be great at this point.Paul

Get a good battery (not one you need to jump every morning). Low voltage (possible bad battery & or Alternator) can cause rough running with no codes. Can you scan 'live' data while running?
