Ok so about 2-3 months ago I ended up overheating my truck while driving around town. Cant believe I didnt see it but is what it is. Previously I have swapped the radiator, upper & lower hoses, heater hoses & bulk head connections, water pump, thermostat & full flush. When I did all of that I had one of the heater hose replacements with the Dorman metal/aluminum connections didn't seat correctly & wouldn't hold the seal so I swapped that one hose back to the stock with the intention of going back & fixing it later. Course that didn't happen & its what failed completely. So I get the truck back to the house limped it home with gallons of water & some hose crimps. Once I got the hose fixed correctly, refilled the cooling system & cleared the codes the truck will run fine but then every once in a while I will get a P0300 random misfire. Sometimes the trac & stability go off as well, the truck will shudder & run kinda ruff for a minute & then it goes back to normal & the check engine light goes off. I have done the head gasket check with pump & fluid thing that goes on the resevoir. Ive also pulled the plugs & checked gaps & looking for any impacts on them & they all checked out. Along with doing a compression test. All cylinders between 200-212 psi. What am I missing? Bent valve or push rod maybe or something else?? I'm stumped. Truck has about 150K on it.
