i just got back form about a 50 mile trip and on the way home my oil pressure started dropping, but only at idle and only when its in gear. at all other speeds the oil pressure is normal? is it a bad pump?

Could be the oil pressure sending unit but it could also be a bad pump. I had a Mopar once when the pump went bad I was running 30 lbs at cruise and basically 0 at idle. Much easier and cheaper to replace the sending unit first and then see where you're at.

Put a mechanical gauge on it

check your level!! this happens to me everyso often but i top it quick. normally ill notice the pressure drops when shifting say, 3500 2nd to 3rd... even clutch in to come to a stop. normally a rev brings it back up.
