Alright y'all, she's back with a vengeance. Hot air hose has been installed. The truck ran perfectly all week, until the snow hit. Now it's back to bogging down, so I'm thinking the active snow may have something to do with it?
I also had the CEL come back on with Code 13, but the O2 sensor was just replaced. What else would cause a code 13?
I've also noticed it's running colder than it should be according to the gauge in the cluster. I've replaced the temp sensor next to the thermostat, next up is the one on the driver's side of the engine. Does anyone know which one sends the readings to the gauge and which sends it to the ECM?
new doesn't mean its good, these days. what kind is it? was it heated?
I used an AC Delco professional 02 (heated) sensor for my replacement.
