funny,but just recently my guage started going to about 1 unless i was using the throttle and then it would close to 3.as far as i can recall it was always at 3 while running but just the other day -after idling for about an hour -i got back in and noticed it was idling around 1 and only at 3 while under power.could i have done something wrong by idling or is my oil sender just about to give it up?
