The air filter needs to be clean also. How is it malfunctioning?


After installing mass sensor, car ran good for24 hours. Then check engine light came on and car started trying to stall and run rough. Replugged sensor and will run good another day be for acting up again

Is there a code related to this?


Yes, what are the codes you are getting? MAF's rarely fail. Sounds like a vacuum leak.
