Hey ive got a 1995 max and ive been haveing some trouble with it. First i was getting a code for ks and ft o2 so i replaced them both and reset my ecu. The knock sensor code came back and it says replace or check harness. Well the ks is brand new so i no it doesnt need replaced and the harness looks fine. There is what looks to be like a relay connected to part of the harness and has something to do with the ks anyone know about this. Also i get P0300 Engine miss fire ive ran injector cleaner and im about to have the injectors cleaned at a shop, ive also checked the spark plugs their fine. My car doesnt miss that bad its got a small miss u can here in the exhaust it effects the car mostly in the 500-1500 rpm range. It will hesitate and sputer a lil when u try and take off, has anyone had any previous expereince with these problems or no anything that could help me fix the problem?

 

Try checking your coilpacks. I doubt your KS harness is bad, but you never know.
