I replaced my oil sending unit, filter and oil and the oil pressure gauge is stilling acting up. It is going from 40 to zero and then to 20 then to zero. Then, the stop engine light comes on at zero. So, if it is not teh oil sending unit then what could the problem be?
Thank you.

Have the oil pressure manually checked. See if it's apump acting up. It could be a harness shorting out some place. Or a gauge as well. Could be a bad oil filter as well.
