P0300 Code, Shaking, Flashing CEL after failed lifters replaced

[Western96]

The AFM lifters in my truck failed earlier this year with only 60,000 miles on the truck. 3 months and around $5k later, I got the truck back from the dealer. Now, about a month or so later, it has started having even worse engine problems.

 

The truck shakes a lot at low RPM and the idle is much lower than normal. Got a flashing check engine light a few days after it started happening so i can’t drive it any more. I got a code P0300 - multiple misfires and P050D - low idle.

 

Any idea if this could be related to the dealer doing shoddy work with the lifter job? It seems like there can be many reasons for a P0300 code and some of them could be related to the lifter work.

How many miles been put on it since returned from the dealer? With only 60k miles on it when it went in and already codes and a failure this soon highly suspect the dealer didn't do something right. They surely warranty their work. If they give you the run a round ask them for their district service managers phone number and contact information. Go up the ladder and complain.
