So i recently swapped out my stock cam for a cam with a .505/.515 (intake/exaust) lift and now it has a really rough idle and sometimes dies and when i give it a lil gas it falls on its ass.. I know i have a bad throttle body gasket and i uploaded a stock DHP file with my DHP powertuner and the crank learn code (1336 i think) appears with a no rear 02 sensor code (no rear O2 sensor so its legit).. Those are the only 2 codes i get, i think maybe i am off a link or tooth on the cam gear???? Any fresh ideas before i tear it back apart???? Would the crank learn not being performed throw everything off??? You got any ideas for me???
