I have an LS2 (2005 Pontiac GTO) in my Datsun. I believe I need to run the crank relearn procedure as I get codes for both the crank and cam sensor (yes, I replaced both). It runs smoothly after start up so I believe the motor is in time (I had an experienced machine shop do the timing). The main problem, apart from the codes, is that the motor doesn't like to start (it turns over, occasionally back fires, but eventually starts up and runs well).
I tried to run the crank relearn procedure but it says it cannot run with codes present. However, I don't see any codes in the scanner (after clearing the cam/crank sensors). I'm new to HP Tuners so am I just missing something obvious?
Thanks!
