I had the same problem with my 99 limited. Check engine light came on on the way home from Canyonlands and the code read "system too lean". The guy at NAPA said it may be due to the 85 octane im using in CO. Im gunna start using 87 and up and see if it goes out.
hey guys,
Im new to the forum and i have a 99 limited 4runner with the locking diff. I love the truck and living in CO it serves me well. My check engine light came on yesterday on the trip back from Canyonlands Nati Park. I got it checked today on a diagnostic tool and the code that came up...
