I have a 91 rs and the oil light blinks like a signal aall the time. I checked the oil and it is full. Any ideas?

 

may have to do with oil pressure. sorry im not sure. As long as oil is full i wouldnt worry to much about it. maybee bad sensor? to many things.
but a quick fix would be to put electrical tape over.

 

either ur sending unit is bad or u arnt getting good oil pressure. id change sending unit and see if it still blinks if it does u problly gonna need a pump and a oil flush. U can pick up a sending unit from a junk yard or if u have a friend with a DA just borrow theirs
