Yesterday the oil pressure pegged at idle then went to down at driving rpm. Every time I stopped it pegged then dropped to near normal reading at driving. I thought the filter by-pass might be plugged but after a filter change the problem is the same.

Check the oil pressure with a mechanical gauge-if normal replace the oil pressure switch-if abnormal could be the oil pump/engine bearings
