Just installed a crankshaft sensor on a lumina APV.

1. remove 3 bolts from cover under the flywheel so you can use a visegrip plyer to hold the flywheel from turning

2. remove the serpentine belt

3. Jack up car to remove front right wheel, and plastic cover to gain access to the crankshaft pully

4. Remove bolt from crankshaft pully ( you will need an extra stong breaker bar to loosen the screw.

5. Use a large pully remover to get the pully off 6. the cover over the sensor will pull off, try no to break it. 7. remove a screw that goes up vertically to lock the sensor in 8. wiggle and pull the sensor out.

Reassembly proved to be very easy

My 1990 Lumina 3.1 had the same problem and it was caused by the crank sensor.

The oxygen sensor is usually mounted in the exhaust manifold pretty close to where the exhaust pipe bolts on.
