My car has been running like CRAP for the past week ever since i got the CEL for a knock sensor P0325. I've tried using a higher octane (91) gas to see if that was the problem but the car still bogs when i go WOT from a complete stop or on cruise. Any advice on what else i need to do/look at before actually replacing the KS? And how much work is involved in replacing it.
Any suggestions greatly appreciated
