Diagnosing a car for a customer. Currently is having cyl misfire on every cylinder after he installed exhaust and gutted cats on this 03 accord v6. I always recommend before doing modifications that will effect airflow to make sure you have an ecu that can be tuned and have correct tuning for your air fuel mixtures to keep the motor running and healthy. Now he has to figure out if he wants another motor or a different car since he has a hole in cyl 2 piston from lean mixture.
