Mysterious check oil light.

[Shaminii]

Ok, before any Zilvia mobs start bashing, YES I did search. I found similar threads with answers but since they had slightly different cases and not all cars are made equal, I've decide to make a thread.

Here is the story:
I took my car out to a drift event. All was well except a minor overheating problem and right after my last run, my oil light comes on. Please note that I had changed my oil with Mobil1 Full Synthetic 10W-30 before the event. During that run, I did spin out off course and my engine stalled. I can't remember if it was because I didn't put the car in neutral or not. When trying to start it, the car had trouble starting. Of course, right after that run, I freak out once I see the light. I check for any smoke and oil coming out of my car and yet nothing is coming out. I drove the car home and during my trip, I noticed that the light only comes on in a flickering fashion when I'm either in neutral and at a stop. In other words, it only comes on when there isn't much load on the engine. Once the car starts moving, the light goes away. The car seems to run fine and there are no noises or smoke. I check my oil each time before I drive and it's always full and gold. Now, I know I shouldn't be driving the car till I find the problem, but its my daily so finding a quick solution would be great. Also, my idle has been weird too. I've always had idling problems, but now when I come towards a stop, the rpm's would chill at 500rpm for a real long time. I haven't been able to get under the car to check anything since I don't have a jack that is low enough to go under my car. My possible ideas of this mysterious oil light are: blown fuses, loose sensor, bad oil pump, maybe the oil pan got dented. I really hope this is just a minor problem. Help and input is greatly appreciated.
