So i started truck as usual. it was 27 degrees truck hesitated for a second or two then fired up waited for low air light to go out, released parking brake and next the strange part the low air buzzer remained on and the truck didnt want to move pedal to floor and bareley idled. a few minutes later everything was back to normal my question is why did the buzzer remain on? i know why the truck dogged for a minute because crappy govt. stale fuel was probably bad. but the buzzer worries me.
