Hi guys, I picked up the old Volvo 940 non turbo and the oil light stays on at idle. If I give it a quick shot of gas it goes out and stays out.....until I shut the car off and start it again. Hot or cold....the light stays on at idle....and will eventually go out on its own, but usually only after I've hit the gas. ***I changed the oil and filter from a Fram and 5w30 high mileage, to a Mann and 10w30 Dino and it didn't do it for two days.....now after some driving it's doing it again. What are your thoughts? Oil pressure sender? Oil pump crud? Bearings? Either way, this car has so many issues I'm thinking about buying something newer. It's too bloody cold to work on it right now. Thoughts?
