provis Posted July 9, 2009 Share Posted July 9, 2009 I'm having a really difficult time here with the check engine light. Just finished changing the knock sensor and a coil pack for cylinder 6, drove and the light comes back on. this time its P0446. Bought a new dealer gas cap, cleared codes, light came back on, bought Vacuum valve which comes together with the charcoal canister, had it replaced, still comes back on. even the mechanic who did the repair is not sure what it is. tried clearing the codes a couple times still comes back on. Already spend $1000. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
