Engine Mechanical problem
1999 Plymouth Voyager 4 cyl Two Wheel Drive 168700 miles
While driving down the road & get on gas oil light come on. When get back on gas light goes off. It don't come on while idling. Can get on & off gas while idling light don't come on. I took the oil screen off. I thought it might be clogged up. It was clean & open. I clean it any way & put it back on. I put a new oil pressure switch, new sparks plugs, & plugs wires on it. It still come on when get off gas while driving. I use H avoline 30HD oil in it. Any suggestion? Thank you.
