Engine Mechanical problem
1990 Oldsmobile Delta 88 6 cyl Two Wheel Drive Automatic 157980 miles
When the car is parked for more than a day, it will run fine for about 10-15 minutes and then will cut off. If I wait a few minutes it will start up again, run for a few minutes then cut off again. I have already changed the oil filter and it still has not gotten any better. Any clue as to what it might be?
