Rough idle/no rev problem

That's an interesting idea that made me break out the Google machine. I do have a slight oil leak that is not the spark plug tubes (replaced), not the camshaft plugs (replaced), not a RMS leak, and appears to be coming from under the passenger side air plenum. So as I understand it, there is a oil pressure/temperature sensor under there next to a knock sensor. But doesn't that just drive the gauges and send info to the DME? Would it really cause the idle/stalling problem?

My thought is this, low oil pressure is locked out for start up, but I believe times out if low pressure does not clear in specific time. This may shut down the fuel pump. This is typically a safety system so if car gets in wreck and catches fire the fuel pump doesn't continue running. Just a thought.

It's a great idea. The part is cheap. Access is a pain, but removing the intake manifold for cleaning may solve that. And if it is leaking, I'd like to correct that. Thank you!
