20 Most Recent 1991 Oldsmobile Ninety Eight Regency Questions & Answers

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.

its possible. to know it will have to be checked out from the crank and cam sensors and ignition module to the ECM to know for sure.

Starting in 1991, GM used a speed sensor on the side of the transmission instead of a speedo cable.

You have to take the inside door panel off on most cars. On some you just open the door and their is a clip in the door jamb. I am not sure if your car has this. The Oldsmobile (GM) has good locks though. Very difficult to pick. Purchase a complete lock set off of the internet that are keyed the same. Take off the inside panel. (a few screws and lots of clips) The window must be down to remove the panel from the window hole. You will have to reach up and grab the clip on the back of the lock and pull it towards the side. (prepare for knuckle cuts and bruises) The window must be up to remove the clip from the lock. There is a tool for doing this, but it is expensive. I usually use plyers. Good luck.

Some locks are held in place by a nut. (10mm) but I am pretty sure yours is a clip.

Most likely the float in the tank is stuck. You'll need to pull the fuel pump out and fix the float.
