The Check Engine Light may illuminate, the engine may run rough and have misfires on acceleration. Commonly the ignition coils and/or the ignition coil boots are the cause of this problem. The rubber boot that insulates the coil to the spark plug can dry and crack allowing arcing. Inspect the coils and boots, and replace them as needed. Our technicians also recommend replacing the coil boots any time the spark plugs are replaced.
