Okay, here is the problem, i bought my 1990 loyale at the beginning of the summer, its a manual 5 spd, EA82, push button 4wd, throttle body injection, only got 163k on it and runs great, but ever since i have had it, its had an erratic idling problem, it will idle up to 3000rpm after start and i have to tap the gas to make it go down, sometimes between shifts the rpms rise up, then lower when in gear, but on hot days it wil idle down to 1500rpm, ive heard lots of older subaru's have this problem, any help or suggestions would be appreciated, thanks!
