my oil gauge in my truck was acting up, goin all over the place at stop and just bombin out on me occasionally, and it always read real high oil pressure, so i read up on and it found that if i change the oil pressure switch it'd fix it. I changed it yesterday and it stopped goin over and is in one place until i hit the gas, but its still reading way high on the gauge. From what i've read you want it around 40 psi stopped but mine is sittin at around 55 psi and 60 somethin when driving. What else could fix this problem?
