I didn't get the barrel out but I did take the magnet/plug end off along with the other end that has the spring. It all went back together easily. I think I found the problem with the throttle body. I'll try and get a picture up Monday.
There is a visible gap around the entire valve. you can see it contacting the side of the throttle body in a section about 1/2in long. The valve has no side to side play.
Can I loosen the two screws holding the valve and move it a little?
