www.club202.com has some good threads on OVP and Crank Angle Sensors.
mpoli - it's the craziest thing, I put in a new O2 sensor I my car starts quicker then I can remember. I used to think my Crank Angle Sensor was going south but since the new O2 the starting is amazing. Cold or Hot the starting is better. Of course I have no data or way to prove - or it could be coincidence
