That flat spot is probably not due to the throttle body. Also check the timing is not over advanced and look for vacuum leaks. The injector seals and where the intake manifold pipes meet the cast base are sneaky leak areas. Especially if the pipes are rusting.

Subject: Looking for a Known Good 1.9 Throttle Body

Hello all.  In a continuing effort to make my Vanagon easier to drive, I am looking for a known good Throttle body.  I don't really have the $ for the
$300 rebuilt unit at this time (although I will be going that route if pushed).  I can no longer adjust my idle speed, that's how worn out my current throttle body is.

If anyone has one of these to sell, that is known good and not worn out, I'd love to buy it.  I'd love to be able to set idle speed, and not have an outrageously annoying flat spot off idle.

Thanks.
