oil pressure gauge fluttering
another issue that has come up within the last few days. my oil pressure gauge will often flutter, from its normal range to nothing.
it does this when:
1. i put the truck in 1st/reverse from a dead stop
2. when i put a moderate load on the engine (RPM doesnt apparently matter, i tested this tonight from 1500 to 3000 RPM).
3. when im idling on an upward slope (idled at taco bell and i found it constantly moved around until i revved it up to 1500, at which it stabilizes)
another oil check is due tomorrow, but other then that im not sure what to do (havent replaced that fram oil filter yet)
