1. Inspect the spark plugs for correct application, there should be platinum spark plugs installed. Inspect the spark plugs for any signs of misfiring, such as carbon tracking on the spark plug insulator or the coil boot. Inspect for cracked spark plugs or incorrect gap. Inspect for any kind of fouling on the spark plugs. Replace the spark plugs or the coils as needed.
2. Verify the wiring is not shorted to ground from the coils to the Powertrain Control Module (PCM). If the wiring is OK then the problem is a bad PCM. Be aware that this PCM comes blank and needs to be flashed for it to run after replacement.
