I have been putting oil in it, i put 3 qrts on sunday, I don't have much money to fix it so i just get by trying to keep it running. the check engine light is on because of emissions problems, looking into getting new cats for it. Two oil lights came on, but only intermittaley. And when it finally wouldn't start a light came on that I have no idea what it was, its square with lines. The last time i checked the oil was sunday and it was fine, i haven't checked it yet, was just trying to get it home last night(2 miles at the most) to put oil in it there. Does it have a sensor that would detect oil pressure and turn off the car?
