Is it a constant misfire? Does it misfire only under load or at idle? Was there any other repair work done prior to your problems? Are there any trouble codes being stored in the PCM other than the misfire codes?





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

TRhat sounds like coil circuit codes. What are the exact code numbers?
