I’m looking for that small wire that connects to the knock sensor on one side, and to the engine ground on the other side, its like 2 ft. long. It has a yellow and black wire coming from the knock sensor.

My black wire is not there anymore, so the car’s pulling timing and running rich. It prob has code 34 too, but I can’t check it ATM.

Thanks guys.
