I own a 1996 Camry 4 cyl with about 200k. My check engine light is on and as it turns out, I needed a new Cat Converter and Knock Sensor to be able to pass emissions. (Gotta love North Carolina laws) The only problem is that I can't find that Knock Sensor to save my life. It's supposed to be on the front of the motor right by the intake manifold but I just can't seem to find it. The only thing that looks to be remotely close has a different plug than the replacement I bought from Autozone. Any help? Thanks...
