I have a 1999 chevy silverado with a 5.3 motor. I was getting codes for system too lean bank one and bank two. I replaced my intake gaskets and since I had the intake off I also replaced both knock sensors. So far I have no system too lean codes. But now I have codes for the knock sensors. Codes are po327 and po332. Knock sensor bank one and bank two circuit low input. Could there be a chance that both new sensors are bad? Are the sensors maybe not torqued enough? Or is the wiring bad? I was told to replace the wiring cause the wires are exposed to heating and cooling and the metal in the wires broke when I moved them. Any info would help.
