Under the steering wheel

What is your question?

My 1994 buick park avenue dies when I'm driving down the street and the oil pressure sensor reads low when I'm not on the gas and I just had a new oil pressure sensor put on it.and my car kinda revs up high and low sometimes and then it starts to die but it always starts right back up I have had 3 new coil packs on it a ignition module throttle position sensor oil presser sensor fuel filter it's been dieing atleast once or twice a day and I'm trying to figure out what could be causing the problem

What makes this problem better or worse?

It gets worse when I'm not on the gas and when I'm at a stop light the oil pressure gauge goes down in the red and the red circle light comes on

How long has your 1994 Buick Park Avenue had this problem?

A long time
