LOL, my idle gets worse as the tank level drops. If the light's on it's almost a certainty I'll throw a CEL. Part of the reason I never let the light come onmy idle drops, stumlbes, and stalls right after i put gas in the car
The ugly little whitish/yellow plastic thing that sits on the end of the fuel rail on the driver's side. When I installed the Perrin fuel rail it removed the pulsation damper. I believe the purpose of the damper is to damp (duh!) out oscillation in the fuel flow. Probably has something to do with stabilizing the idle and whatnot.pulsation damper...do explain pls?
