Engine Performance problem
1988 Subaru GL 4 cyl Front Wheel Drive Manual 238205 miles
As spring comes and the air tempertures rise my Gl Wagon runs better. It was 95 degrees air temperture today, it ran perfect. It past the smog test todaywith great marks. The test read that it idles at 698 rpms that is great. This condition leaves every spring and comes back in the fall. Would a disgnositic engine test show the part that has failed? I checked the vacuum lines they all looked and felt very good. I would appreciate you help as this is my work car.
