Many people complained about this issued, and a new prom was calibrated. Mine will come down, but sometimes at a light, it will not come down all the way, before the light changes.

Marc Haibeck makes several adjustments to the linkage and replaces the dag with a spray-on compound. He fixed my high idle TB and its been great for several thousand miles and several years. Once you have sorted out all of the other potential issues (and it sounds like you have), I'd give him a call and see what he says.
Now I see why you have the other post ging for where to get a stock prom --- As you will see in my answer to you on that thread ---
HAIBECK is the man for the chips!!!
