It was 39 deg outside temp yesterday when I took it for a ride. The light didn't come on till the engine was about 165 deg, then would come on during acceleration. The light would stay on above 75 mph even when I lifted till I was below 75. I ran the tank down to 1/4 full then filled with 92 octane with no change on the ride home. I didn't mention earlier that the low fluid light is on all the time, could this be the germlin that I'm chasing? thanks
