Question about 1989 Isuzu Trooper
My on board computer says EGR sensor bad but cant find it in the manual. Does that control the idle? My idle races high and low and doesn't settle for one rpm.
The only thing that can change your idle speed that much is the the isv idle speed valve u have a faulty valve or your computer is faulty
