Systems scanned

  • Engine (OBD-II): responded
  • Transmission (OBD-II): responded

Confirmed results

  • P0171 (stored) — The engine is getting more air than fuel, so it is adding extra fuel to compensate.
  • P0300 (stored) — The engine is misfiring — some cylinders are not burning fuel properly.

Urgency (safety rules)

Stop driving as soon as it is safe and seek assistance — A flashing engine light or active misfire can quickly damage the exhaust system.

Recommendations (not confirmed)

  • Compare short and long term fuel trims at idle and 2,500 rpm
  • Smoke test intake for leaks
  • Check MAF readings against expected range
  • Measure fuel pressure
  • Check misfire counters per cylinder
  • Inspect plugs and coils

Technician observations / repairs / post-repair verification

None recorded.
