I have a 98 Subaru Forester with 350k, and I have been trying to diagnose a rich fuel condition. at idle when I let it warm up it seems that both long term and short term fuel trims are negative. but when I run it at 1500 or better rpms the short term fuel trim goes positive in the long term fuel trim stays negitive
The front o2 is switching , bit it wont go over .5 volt unless you cut throttle the rear o2 seems ok
Anyway it's an old Subaru that just has to make it through one more Minnesota winter Before my girlfriend is considering buying a new car To replace both her insight and her beat up Forester. It gets maybe 15 miles to the gallon. Any insight on a direction to progress is much appreciated
