"The egr valve was stuck open so when we put the block off plate on it ran like a champ, and I am so happy to have her back :)"
Great news. I had the EGR on mine stick open (causing stalling and inability to do low speed driving), why I just made a block off plate for my own B2200. A closed EGR valve can be disconnected and used as a block off plate too.
Remember: in the very 1st reply I stated "Does your truck still have its EGR valve (on intake manifold on passenger side of the engine) ??? A stuck-open, or partially stuck open EGR can cause rough idling and stalling. With your Weber, you don't even need an EGR on your truck (I have a Weber like yours, and made a block-off plate for mine)." So this could've been found out sooner.
