As everyone knows, this was giving me trouble because it would come on as the engine dropped in rpm when it hit the 2200 rpm mark. No oil light at idle, no oil light nor warning horn at higher rpm. Only with a rapid drop of rpm to the 22000 rpm mark. Step on the gas to accelerate the engine rpm, and it went away. Let the engine drop slowly thru 2200 to idle and it would not come on. Changing out the high pressure switch by the coolant pump pulley SEEMED to do the trick. Haven't a Had an problems so far. But changing out that switch was a bear - but thats a whole 'nother story!
