I have a 1989 Bonnieville LE
Could you please tell me where the Cam sensor, Crank sensor and knock sensors are al located. Also the oxygen sensor? Are these things that a do it your self person could do or would the car have to go into the shop for replacements? Thanks Lori

cam shaft sensor is on the upper left side of the harmonic balancer.

i have 1 that wil fit the "C" vin code off a 88 LE and it doesn't even have 500 miles on it.
i got it at Oreilly'* for $29.99 plus tax i'lll sell it for $25 shipped to lower 48 states.

i developed rod knock and replaced the motor

EDIT: oxygen sensor: if u look on towards the back on the black plastic paneling in the middle u'll see a wire look straight down at ur exhaust and thats ur oxygen sensor plugged in to the manifold i have 1 of these also.
i got it at Oreilly'* for $21.99 plus tax if u need both i'll give u both for $40 shipped

the camshaft sensor all u need is a 10mm socket or wrench and the oxygen sensor u'll need oxygen sensor socket and ratchet u can usually borrow both at an autoparts store.

Thank you. I live in Michigan 48183. I am very interested in the parts. Can you e-mail me at wwwN8VBKk@sbcglobal.net Thank you
