Hi everybody! Just wanted to introduce myself and beg for help. I'm getting both the p0332 and the p0327 knock sensor codes in my 2000 z28 that I just bought. I need 1 of tony's knockout boxes but if I can't get 1 then I need any help I can get. The car has headers and deleted cats and I'm about to cam it so the false knock isn't going to go away. I really don't wanna spend 140 bucks on new Delco sensors and do all the work for it to just have the same issues after. Any help I can get would be great, I traded my 62 gmc for this car and am not used to new cars and there computers
