Ok, well my car has been running rich lately and fouling out plugs, and i was doing some looking around on the fuel rail. I took the cap off of an item, which is some type of fuel dampener on the back side of the fuel rail, and noticed that it had a tiny screw in the middle that had come out completely of the hole and was laying there, but the cap kept the screw in the area. can this be a problem?:1zhelp:
