Pull a copy from the web & give it a try FIRST.
Note: this tends to be typical if there has been a battery related situation (dead, replaced, etc..)
I took it in for a third time and like a dummy told them that someone said it could be a map sensor. And guess what magically that was the problem. I was charged another 117, now im broke my car is still doing the same thing and I feel I have been wronged. When I try and start it it hesitates most times, sometimes it will try and cut off right after taking off and sometimes it runs fine. I dont know what to do and I was wondering if anyone has had this problem or can give me any suggestions?
I checked the code and It does not give one.
What could the problem be that the code light keeps coming on and no code?

The contacts wear and don't make contact.
The key gets dirty.
The wires break strands where the steering column bends with the tilt adjustment and that changes the resistance of the strands; that means your wires may break completely sooner rather than later.
Here is a link. Just search for VATS and you'll find a plethora of solutions.
You find the orange tube that looks like a wire that has two fine wires inside. Note where it plugs in. Cut it with extra wire away from the connector. Solder in the resistor pack you built after measuring resistance with a meter to see which of 15 you have.
Note that you connect the new resistors to the wires going to the connector--not the wires going up to the steering column.
Car alarm places get premade resistors in packs for the 15 GM values. They are used to bypassing to let their alarms do the work. That might be an alternative if you don't like lying on your back to get to this stuff.
There also is access through the glovebox after you take it out. The theft deterrent module is over there that the wires go to. You can cut the proper two wires there and insert your resistor pack. The resistance has to be with 5-10% of the original values.

Since it starts right back up, that's a problem. It would be better if it had to sit for 10 minutes before something changed and it started. You could pull a spark plug wire off and lay it on metal with an old spark plug in it to see if you were getting spark.
How many miles on the car?
How's the battery? Any chance it's the connections or the cables at the battery? For a time a few people had battery posts that would lose contact, like they were broken inside. And the cables corrode with corrosion between the separate contacts on the positive.
If you take off the cables to clean, first put the heater in OFF if you have the automatic control system. Then remove cables.
A remote guess is the crankshaft position sensor under the edge of the harmonic balancer.

It could be a few cars have had trouble with ground on the end of the ISC under the coils. Clean contacts.
But the other thing that comes to my mind is that 1994 and 1995 seem to have a few more reports than typical of PCM problems. You might clean contacts at the PCM or replace it with a junkyard piece or just switch from another leSabre, if a friend has a similar one, to see if that fixes it.
Just from listening to Bonneville and leSabre (and a few Olds) people with the problems in other forums, I'd guess PCM. The odd thing, if your sense of the timing for the oil light to come on so quickly is right, is that the engine is not dying and the oil pressure dropping causes the light to turn on after the revs drop. Instead, it's being reset by a complete drop in voltage or the PCM.
It might be worth running a long line to the positive terminal for power away from the battery and using a meter inside the car to watch for voltage drop at the time the problem happens. I'd suggest using a ground out on the motor or on the computer box area. That might catch if you're losing B+ or ground at the PCM.

Thanks for reporting back. That may help someone else with a related problem when they read the forum.

This sounds like the exact problem that I am having. Sometimes the engine will shut down leaving the change oil light flashing, I will about ten and it will start right back up again or sometimes you can see the electrical system shut down, the change oil light flashing and come back to normal. After you have replace the PCM any further problems? Thanks.
