What causes Oil pressure to flux? Oil Level is good (right at the full mark). It reads high but still in the normal range but when ever I put torgue on the engine it'll go into the high range for a few seconds andthen come back down into the "high normal" range. Gauge doesn't really move with car in out of gear and me revving motor only when I go from a stop or if I put my foot into it. Also the engine temp fluxes from right in the middle of the gauge to "hot" when I romp on it. whats the deal?
