I have a 93 Chevy 1 ton dually with a 454, and I noticed a miss after it warmed up. When it misses, the oil pressure gauge spikes. It does this while driving, and also at idle. When idling, it seems like just a slight misfire. The oil pressure gauge normally sits at 30, in the middle of the gauge, but when it misses, it will spike all the way to 60. What is causing this???
