ok finnaly got home to check some things out, and while i was listening to it run , at about 2500rpm and nnoticed the rpm gauge was not compleatly stable, it went up and down a lil bit, while trying to hold it steady,,,

Also to my suprise, and i would throttle it, i physicaly watched the oil guage reach beyond the 80 psi mark, it literaly went of the chart, not for long just goes over and comes back,,,even if i rev to 3k rpm and hold it will register far over then back to a decent psi! oh "fyi" it never drops to low, just shoots real high for a micro sec,.,.,. What does this mean??

 

mine did that, turned out to be my oil pressure sender
