Re: Help
Actually a dirty throttle body will cause low idle stumble problems and stalling on any vehicle equipped with drive by wire throttle bodies and set no codes, if it gets real bad it may set a correlation code. A plugged cat will cause misfires and set a p0300 as well as turn on the ses light. A plugged air filter will set a lean code if pluigged enough to cause a drivability issue. Anything is possible though but these are my experiences working on these trucks everyday
