AA did a great job of fixing my top end after the dreaded AFM failure. Thx GMC for such a flawed system that breaks on almost all these series of trucks. All new lifters and push rods. Expensive fix, but well done. After the job, the o-rings on the injector(s) were leaking causing a pfft sound. Paid to have that fixed with new orings on all eight existing injectors, but after that, one of the injectors was running really rich and caused a permanent check engine light. Cory agreed to cover all the labor to swap out all 8 injectors whereas I covered the cost of brand new GM OEM injectors. A fair deal I felt. Dutch is a great mechanic.
