First I had no codes car was running fine. Replaced water pump and timing belt and replaced wires and valve cover gaskets. After that code 52 popped on and I could not figure out why. So decided to change the knock sensors and harness wire and starter. Still code 52 pops up but we noticed it pops up only when I slightly excellerate or check engine light comes on and slightly excellerate. Can cut the car off and runs 2-5 minutes and does the same thing. Can always turn it off and drive a few minutes before it does it again. I remember someone had similar problems and was taking there’s to the dealer. If anyone knows what could be wrong please give me ideas. I checked the ECM and it’s ok. Also changed the rotors ignition coils and everything else still doing the same thing. Suggestions are welcomed.
thanks!
thanks!
