Thank you for all the info" Got the car back from garage and they replaced the Power Control Module and seems to be working fine .

code was po353,found internal short in #3 coil,replaced but still misfire.Thanks for the reply.I am taking it back tomorrow.Will let you know the outcome.

I have a 2007 vibe ,engine light on: had #3 coil replaced and it is still idling rough, and also under pressure , any suggestions
