Anyone have any experience rebuilding a throttle body for the 2.1l engine?
I've come to the conclusion that mine is pretty much shot after 120K miles.
The butterfly valve has worn grooves on the inside of the body such that
there is an air gap around the perimeter of the valve and a lot of slop
along the axis of the pivot rod. The result is an inconsistent idle and
problems setting the throttle position switch because the valve does not
always return to the same position. This seriously affects driveability of
the van around town (still runs great on the highway).

How would one fix these problems? Fill in the grooves with JBWeld and sand
smooth?

New throttle bodies are $515.00 at Camelback and it's going to be hard to
find a used one with low miles.
