Your car is idling roughly, white smoke comes out of the tailpipe, and the engine is putting out less power than usual - but there's no check engine light! What is most likely the issue?

A dirty or clogged fuel injector is likely the cause of this. A trip to the dollar store for some fuel injector cleaner will likely fix this problem.
