The oil light is coming on at idle, but goes off when i just rev the engine slightly. I suspect that it might be a bad sending unit, but I am would like some other ideas, as i try to free up time to get the car to the mechanic. The car has more than 200K miles on it and is seeming still running OK. Actually, the issue seems to be correlated to a recent oil change.
Thank you in advance. Note that i am not trying to take away my mechanic’s business. He has just bought his second boat with what i have spent with him, but i just want to think about what the problem could be.
