I’ll go back and try to trace the wires all the way back to the computer. I took the egr valve off and cleaned it and it seems to functioning ok when I put vacuum to it the plunger is moving. How does the cooling system affect the knock sensor? The engine seems to run fine but I noticed the gas mileage dropped 2 miles/gal.
Thanks for responding.
