I pulled the codes last night and got a 34 and a 51. I plan on just relocating the knock sensor sometime. This could possibly be why I've been having some problems with idle and what not I hope. But on the injector circuit code I couldnt find any problems. I Held a screw driver up to each one and they where all clicking. Where could the code be coming from?
