Did anyone use AFM lifters from rockauto? Truck misfiring on 1,7 bank one after lifters put in. No problems with misfiring before. Tik is gone.

Can't say I have but I have seen new GM ones bad out of the box before even.

 

Did you replace the VLOM in the center of the engine?  How do the spark plugs look?  Any bent pushrods on those two cylinders?
