Scan for codes, review fuel trims, misfire counters, and sensor data to pinpoint the root cause.
Ignition & fuel system service
Spark plugs, coils, injectors, and fuel delivery checks—matched to OEM specs and intervals.
Airflow & emissions checks
Inspect intake leaks, MAF/MAP readings, throttle body operation, and PCV/EGR where applicable.
