What diagnostics? Find someone who has a diagnostic tool that can read data on the enhanced side of the PCM not just a generic OB2 code reader.

Scan for trouble codes using a professional grade scan tool have trouble codes stored, pending codes and "freeze frame" information printed so the trouble codes can be properly diagnosed.
