Question type: Maintenance & Repair

when accelerating  fast the low oil pressure light comes on the oil pressure
gage stays up but when you back off the accelaratore the light goes out as long
as you drive at a normal pace. why is the car doing this.

1 Answer


First thing I would do is get a real oil pressure gauge and make sure you have oil pressure. Check your oil and if it is more than 1 qt low this could possibly cause this to happen. Could be a clogged/defective filter (I have had this happen to me with fram filters) If this all checks out then check the connection at the oil sending unit.
