hmmn sounds just like my 89 900 16v. i haven't relaced my O2 sensor though. my mechanic pulled the computer out and all the wiring, cleaned it all and replaced it and serviced the injectors and the check engine light went away. still idles funny though and it sugres on a trailing throttle going downhill. your tach problem sounds like a electrical corrosion prob. try cleaning the contacts, earths etc. Aaron King <> wrote in message news:#SKKGXqC$GA.322nopsamnbbsa02... > I have a 89 900s 16v and it has been acting strange lately.
