  1. 5.3 misfire

    Just an update. I took it into the dealership to get checked out. They said there was oil found in the intake and all they could do was the chemical clean for $1500 and it's not a guarantee fix. They recommended finding a used engine to swap. They put a new plug in cylinder 7 and gave it back to me. Since I got the truck back I have been driving in m5 and putting it in 6th on the highway. 1000km later it hasn't burnt a drop. Going in for a tune next week. Sent from my iPhone using Tapatalk

  4. I have a 2010 Sierra 1500 with 5.3 afm. It has 217000 Kms so I'm well off warranty. Anyway I'm taking the truck in for the second misfire code since I've owned it. The first one they replaced two spark plugs and installed the updated valve cover. This was at 196000 Kms. I've read lots about these being band aid fixes. Since I will be paying for repairs again what are my options? Is it too late to replace the plugs and get a tune to turn off afm? (Will the damage already be done). Or just let the dealership fix and start saving for a rebuild or trade in. Is there anything I should request they check? Maybe pull the valve cover and check valves or compression.
