Question type: Maintenance & Repair

Idling rough when sitting still and gas mileage has dropped 5 to 8 miles per gallon

435

sounds like a vaccuum leak to me. Check around for any cracked or split hoses. Could also be the MAF sensor is dirty, or a bad injector. Start with the leak first though, usually the easiest to fix.
