Question about 1994 Oldsmobile Ninety Eight Regency
cam sensor is only half of the cam circuit, the other half of the cam circuit is the magnet on the timing chain. the cam sensor reads from the magnet every time the engine completes a revolution,
what happens is the magnet on the chain will break into smaller piece which makes the sensor harder to read every time the engine make a complete revolution.
most likely you'll need to replace the timing chain to fix this.

Based on the information you have given to this point, I am just going to give you a few possiblities. Have you had a tune up done recently? Air filter been checked or changed? I am not in any way trying to sound sarcastic so I apologize if I come off that way.Those would be my first things to inspect if I were ask to look at your car. I would also check fuel pressure and inspect the fuel pressure regulator.I would consider these things and go from there. I Hope this helps you but please let me know if you need more information on what to do next but I may need some more information at that time also .

Easiest way here is to get a paper and pencil
Make a drawing of all your pulleys with the crank on the bottom and Water pump above it, then all the rest of the pulleys . Not which ones have grooves and smooth sides. Now lay the is out in fron fo you and draw a lineat the bottom of the crank and go counter clockwise to about 12 o'clock then clockwise around the water pump and look to you right and see what could be next. My guess is the A/C, counterclockwise, then whats next, continue doing this until you get back to the starting poing of the crankshaft. You may have to try 2 different times, but I'm sure you will get it and compare it with the one Checkers gave you. It may be close in theory .
