Not sure what to do 91 BB 5.9 cummins
1991 blue bird 5.9 cummins was driving down the road then I lost( throttle response)then it would return in little bursts(the throttle response) off and on was only able to go about 25mph and then it slowed down to like 15mph. Wasn't able to pull over since there was no shoulder so i rolled on down the road going real slow then the air brake light came on and it died pulled over and no start. Waited about 2 hours press on the gas pedal got it started and now my air brake light is still on. After I let the psi go up to 120psi when I press the brake pedal the psi falls in little skips.
