2012 silverado 4x4 260,xxx 5.3. Timing tensioner broke off and got caught in cam sprocket causing it to jump time. Was almost positive the afm failed, but ended up just needing timing adjusted. Got new crank sprocket, chain and tensioner, wasn't a difficult job but ran into a few inconveniences here and there. Got timing set and everything using a flywheel locker so I know it didn't move putting the balancer on. Started it and it ran but idled at 3k, buddy had a good scanner and was able to relearn the TPS so that problem was solved. Now I'm getting a crank and cam sensor code and rough idle, I read I need to make it relearn it but also that it doesn't need it. Any help?
