I had an 89, at one time I had the oil sender go bad. After I replaced it,
it read on the high side. Went to the dealer, they had 2 senders available
(non idiot light applications). To verify high oil pressure, temporarily
replace the electric with a mechanical.
As for the drop to zero, hard braking will move the oil forward in the pan
and away from the oil pump pickup, low oil levels will make this worse.
