oil pressure gauge bouncing around, engine runs a bit rough
I have changed the oil pressure switch and it still does the jumping around, my truck a ford explorer sport v6 4.0 the engine at times seems to be running a bit rougher than usual. I have though of everything except replacing the oil pump itself. Is there anything else that could be causing this, i see no oil leaks and the fluid is full, except of course changing the pump
Have you put a manual gauge on it yet and checked oil pressure? It could be the gauge malfuctioning.
no not yet, would a failing gauge cause the engine to run rough. I have lost power at times when the gauge bottom out, i was told that it could be oil build up, from the previous owner lack of oil changes. That the screen could be clogged up,
