It seems like my oil pressure changes randomly whilst driving. I have just figured out its due to the TPS i think. If i let off and roll in gear, touch the throttle the smallest amount so the revs don't change the pressure gauge drops by 20psi then rais d when i let my foot back off. As far as i can tell its only the tps that could be changing anything right? But why?
