oil pressure problem should be checked independently of other problems...Use a good accurate mechanical gauge to check. If pressure is good (no less than 15psi at idle hot (I prefer to see at least 20) check dash grounding, block ground and if OK, change sending unit. Dash and body ground can influence operation of shift and body control modules so indirectly your problem may or may not be related, depending upon what you find while testing. And it could turn out to be a defective module! They are expensive and just plugging new ones in may work, but then again, it might not. I might be totally incorrect on this...that's the value of actually being there instead of doing this by "remote control".
If you read the numerous posts pertaining to all vehicles, you will see that you are not alone with electrical problems...As long as the engineers who design this stuff, keep using "modules" to replace ordinary simple and reliable systems, we will continue to have these problems. Do some testing and I'm sure you will find a solution! (I'm still waiting for someone to make a program for a PC that will give a complete readout of every system in a vehicle, including exact faults instead of general system "suggestions")
Good luck

MAP is usually on the firewall...it's about 1/2" thick by about three inches long, has a vacuum hose and several wires plugged into it.

Go half way between the air cleaner box and the "carburetor". Up the 4" black air pipe, a wire harness plug plugs into the MAP sensor there. Also called MAS air flow sensor.
SOURCE: where is locate the camshaft position sensor on
The camshaft position sensor is located inside the distributor. It is a hall effect swich, simply remove the distributor cap and the rotor and you can lift it out, unplug and replace.
Have fun but beware a bad crankshaft position sensor can cause a false cam sensor code to be set sometimes.
Good luck.
