Okay, I’m not a big car guy, I have a small knowledge of cars and probably a lot less than others but my 2009 Chevy Malibu had a check engine light turning on and off for the mass air flow sensor. So i replaced it. The light didn’t go away, even after driving roughly 50 miles. I decided to replace the air filter, still on. Now, I believe it is my drive belt, (belt under the air flow sensor and to the left of the engine) is making a whirring noise, and stops when I pour water on it. I don’t know if this was a coincidence that it happened after changing the filter or if i screwed up big time. The engine sounds weak, the check engine light is still on and the belt is whirring. Any advice?
And it’s currently Sunday, so taking it to the mechanic is on hold.
