Friend has a 1995 Buick park ave with 3800 series II.
Engine light keeps coming on, had it scanned at a local shop. Came up as knock sensor. The shop put a new knock sensor in, the shop cleared the code. 2 days later car started ******* power light came back on brought back same code knock sensor.
The guy at the shop said, I think you need a new pcm spark plugs and wires coil packs. He put all that stuff in same problem.
What it causing the knock sensor code ití* not pcm spark plugs and wires coil packs. Did not do anything.
Like to get to the bottom of this.
