I have an '01 formy M6 w/ a cam, LT's, and tuned with LS1 Edit(old tune) and HP Tuners(currently used). I have got 5 O2 codes P0135, P0153, P0155, P1133, and P1153. I have gone through many sensors trying to get rid of the problem. Also I have a high idle when driving, usually around 2000 rpm's. I adjusted the screw on the throttle body a little to help it already. So did I get a half assed tune or is it something else? Any way I can fix the problem?
