Have been having a reoccurring P0170/P0173 (P2017/P2086) in my '01 SLK320 (same chassis/drivetrain as Crossfire). Have been told that when in a long hot idle (takes about 150 minutes) the Secondary Air Injection is supposed to come on and correct a long slow move from a near zero STFT in both banks to +25 (Torque Pro) which trips the codes. Has been mentioned that the Secondary Air Injection i(SAI) is supposed to come on to correct this. Mine is only coming on when cold and not when hot (added a LED to tell when on).
Have replaced MAF (Bosch, 2x), O2 sensors (2x), plugs. No vacuum leaks, gas cap good, all rubber excellent.
People here seem more technically knowledgeable than other foums & need local (Central Florida) help if possible..
Have also been told that something the the ECU ID indicated it is corrupt. Is this true?

If I need a new ECU my only option is the 5 speed automatic transmission. Does anyone know/have ? I've exhausted my capabilities.
