Parking prawl 99 Oldsmobile 88 - 1999 Oldsmobile 88

It sounds like you are having a problem with your parking lights not turning off on your 1999 Oldsmobile 88. There could be a number of causes for this issue, including a problem with the light switch, a fault in the wiring, or a problem with the light bulbs or sockets.
To diagnose the problem, I recommend starting by checking the light bulbs and sockets to make sure they are working properly. You can do this by replacing the bulbs with new ones and checking the sockets for any signs of damage or corrosion. If the problem persists, it could be an issue with the wiring or the light switch.
If you are not comfortable performing these checks yourself, or if you are unable to identify the cause of the problem, I recommend taking your car to a mechanic for further diagnosis. They will be able to identify the cause of the problem and recommend the appropriate repair.

Possibly a bad switch. Those old rocker switches were not known to last very long.

Check IAC valve and basic tune up items.

parking prawl in transmission not engaging or the linkage needs adjusting to get the parking prawl pushed up far enough to engage.

I dont really see your question as posted.

However, if your headlights are not lighting, you probably need to replace the headlights...

Although power to other outside lights, running, parking, etc...
Would be the listed under EXTERIOR LIGHTS

The Oxygen sensor is very suspect. it is easy to damage on install, even with the correct tool.

Put the old one back in and test the car...

Sounds more like brakes, Possible springs or wheel cylinder.

It certainly sounds like something has become disconnected between your gear shifter and the transmission. If your shifter is in the floor, just take the cover/housing off and check it out. It will probably be fairly difficult to see anything from underneath the vehicle. Hope this helps. God bless!

Only a owner, or somebody who worked on an olds can give a full answer. Well, in London I don't see many Oldsmobile.
