So he is having the cam sensor p0340 tripping all the time, after replacing the sensor, replacing some NASTY what i believe to be original plugs (263xxxkm) cleaning a dirty dirty maf and general things, the code comes back as soon as you rev the car to 4g range. Also the tach also does some crazy things, just just jumping around, the trac/loss of traction light comes on, the traction control light flashes, and these things are in always there till you clear the code.

So my question to useyournoggin, is what do you think the issue is here... im thinking the cam chain tensioner took a puke, and is causing wonky timing... or it jumped a tooth. The engine isnt noisy like a failed tensioner though.

So any and all suggestions, would be amazing

Thanks
