Need help finding the solution to an issue I'm having. So on occasion the engine will run rough and blow a white smoke but eventually will stop. Only happens at an idil. I recently changed out my main head exhaust with long tubes was thinking maybe run a fuel cleaner or change out the spark plugs? 04

Pcv valves? Did you retune the truck after the LT install?

Don’t know about the running rough, but second on the PCV valves. If your oil hasn’t been changed regularly, valve covers may also be necessary.
