Thank You MaasalWarrior. I will check that out.

Good morning. I have a First Generation Subaru. 1990 Subaru Legacy Wagon 5 speed manual with a 2.2 engine. Normally this car runs awesome. But lately, I have been getting Erratic Idle after it warms up. When I stop at stop signs and red lights the RPM will surge. The car is coming up on 277,000 miles. This car does not burn a drop of oil between changes. Has anyone had this problem? How often do you change the spark plugs because I put a new set in last year? Thanks for any help. Bob
