P0327 code where do I start?
I started getting this knock sensor code about two weeks ago shortly after my buddy did some welding on my exhaust. I have searched for some solutions, but can't find any, other than replacing the harness and both knock sensors. I was wondering if the welding could have burned something up even though I unhooked the battery when we did. I've reset it many times, but it keeps coming back. I'm gonna check my harness and the connector on the PCM here shortly. The car seems to be less powerful also, but I haven't logged to see if I'm losing timing. Thanks
