(1) See CIRCUIT TESTS for appropriate test procedure.
(2) DTCs P0300-P0304 can be used to diagnose various symptoms. Go to CIRCUIT TEST HD , step 1 for an overall check of engine condition and inspection of fuel, ignition, and vacuum systems for cause of misfire.
(3) Go to CIRCUIT TEST HF , step 1 for concerns of catalyst system efficiency caused by improper fuel, oil contamination, faulty engine sensor operation, engine misfire, etc.
(4) Go to CIRCUIT TEST JB , step 1 for diagnosis of engine misfire caused by faulty ignition system operation or engine mechanical problems.
(5) Replace PCM.
