Default Re: Knock sensor help

I had a similar problem about a year ago, the dealer ended up replacing the Catalytic Converter under warranty... no problems since then. You stated that it was a GM certified shop? Was it a Dealer? Did they diagnose your problem with a Tech 2? if not I would find a technician who has one and get the codes read by someone who knows exactly what to look for. just my .02c worth Good Luck!
