I just purchased a 1991 K1500 4x.... the previous owner rebuilt the 5.7, and add a mild cam along with an eldelbrock intake. Small problem, the cel is on, and the code is for the Knock sensor. If I am correct, teh bigger than stock cam has set the code....is there a way around this. Long time sence I played with a Chevy. Anty and all help is apperciated!
