I have a 99 911 and last year I was getting a CEL 1531( Cam Adj Bank 1). I had it checked out, everything came back fine. Both my actuators work. This year the CEL came back and now it was 1531 & 1340 ( Timing Chain out of Position Bank 1) I had my timing checked and everything is where it's supposed to be. The car does not work any different that when the CEL is not on. I'm just wondering if anyone has any ideas as I'm getting tired of taking my car to garage and spending money on NOTHING... I've spent close to $2000 in the past 2 years and 2 mechanics telling me my car works great and we have no idea why these CEL's are coming up. Maybe a sensor? Computer?
