I ran my truck not very breifly (boiled the coolant) and how it seems to have a good bit of power loss across the power band, but especially at the higher end. All the fluids look normal, so I don't believe I've blown a head gasket. The truck isn't throwing up any codes. It's a 1990 k1500 if anyone has seen this before or has any suggestions I would greatly appreciate it.
