Hello,

I had codes PO351 and PO353. Replaced
spark plugs, coils, upper and lower intake gaskets, cleaned throttle body, replaced IAC valve, and TPS. Still threw codes,
and was told it was a damaged PCM. Shipped to circuit board medics for repair and just got it back. My question is do I need to replace coils again before installing pcm? Was told a bad
pcm could damage new coils, but I thought it was only the other way around.

Thank you,
Scott
