Symptoms: A faulty MAF sensor can cause rough idling, sluggish acceleration, and high fuel consumption.
Diagnosis: Cleaning the MAF sensor with an appropriate cleaner may solve the issue if its just dirty. If the problem persists, replacing the MAF sensor is recommended. MAF sensors are available from both OEM and aftermarket sources in major cities.
