mine is a 97 K3500 F VIN. I took it to the dealer this morning, waiting to hear back.
The engine is as clean as I could get it. All the spots I could get to are free of dirt and grease.
I'm getting -2.46 TDCO
with my TDCO reading -2.46 in car-code, will I need to move the pump to retard the tdco?
I'm debating if I want to try to do it, or take it to a dealer to do it. I'll be towing this summer, so it needs to get done.
