Hey guys

So i changed the oil in my 97 RS today and after changing it i started it and it starts up but after 2 or 3 seconds it shuts off and i hear a rattle from what sounds like under the gearshift/console (right about where the oil pan is) it was running and holding idle fine right before the oil change now it does this... Do you think changing the oil might have knocked off the tube and it is this rattling inside my oil pan? I will mention i was having an issue with the oil pressure reading really low like 0-10 psi before the oil change but it did run and stayed running...... Suggestions? Thanks!
