Question type: Maintenance & Repair

I have a 2000 Saturn with a 1.9 litre engine that was running fine! Now my idle fluctuates dramatically and the gas mileage is terrible! What can I do to check the MAP Sensor or troubleshoot the problem?

Go to AutoZone or Advanced Auto Parts and have them read the code for free.


Couldn't hurt to clean it and the throttle body anyhow, it usually helps gas mileage in a vehicle as old as yours.
