Oil light problem

Hi, maybe someone can help with this weird problem. I have a CRX SI 91, and it is giving me problems with the oil light.

If I drive normal speed 55 mph, no problem, but if I speed and drive faster and they stop the oil light blinks and from that point on If I accelerate the light turns on y I stop and rpm are below 1250 the light blinks again.

My mechanic and I revised the oil pressure and it is ok, so we decided to change the oil bulb, and still having the problem. I don`t know if it can be electrical.

Any one has been through the same problem??

Any suggestions or comments are welcome please.

Thanks,

Just sounds like a loose wire thats getting a connection when the engine rocks back and forth...My 99 aurora has the same problem...itll go from 120 to 0 and then right back up when you let off the gas...
