it was my fuel pressure reguator that went bad on mine i was pushing 60 pounds of pressure when mine went out and the car was acting like it was skipping and back firing and it was the one with the plastic cap on it holding on my fuel line and there is another on that has a vaccum hose going to it i just ordered a bolt from honda to by pass the plastic cap one so now i have just one i dont know why they put 2
