Connecting 'vacuum amplifier' causes hesitation off idle

See my new post on EGR as I found a workaround and a repair that seems to work fine. Remember no egr at idle! Look at pintle at idle and pull vacuum line. Did it move? It should not warm and deffinantly not cold as the thermo valve will block vacuum to system under 125F. If it just unseat with idle vacuum, try and adjust pintle height if equipped. If not, reroute egr vacuum off of the bad amplifier onto ported vacuum off carb or T it off ported line to distributor. This won't help wot (amp has wot check valve ), but it will clean up a rough idle with a bad amplifier.
