CKP relearn with my Tech 2, issues!!
 

Hey guys I just replaced my PCM with a new one and I have
never done a CKP relearn on a GM vehicle before. I do have a Tech
2, I am following the procedures as they are laid out, but I cannot get my
car to do a fuel shut off at 4000 RPM. Vehicle is a 2002 Camaro Z28 -5.7L LS1 - Automatic 4 speed. It is telling me to go WOT until a fuel cut off, only problem is my car is not doing a fuel cutoff. It is all stock. Anyone???

I have the common P1336 DTC code that will not fawk off until I do this relearn and
my car runs like shit. Any info I will be appreciate. I have been searching everywhere
for an answer and nothing. Thanks.

Doing crank relearn has 0 effect on the car running correctly. If it's running bad you need to get to the bottom of that problem first.
