Front cat recently replaced; old one broke up, plugged up exhaust. Ran fine for a week, then ran rough lost power; DTC- "random misfires" Got tune up, several new coils, including cyl 4 and 5.
A week later, "check engine" light on again; it runs fine, but codes say misfires on cyl 4 and 5 and front cat is bad.
Had codes cleared, drove about 200 mi, and same error codes come up again - misfires on 4 and 5, front cat bad. Meantime, it runs great! What's the problem" Could PCM itself be bad?
