BAD EGR?

[BRONCADONK]

just a quick update, the tomco carb just needed a little wd40. i lubed the linkage and kept working it with the motor running. it finaly loosend up. now it purrs like a kitten. i'm getting a steady 20 on the vac guage. all is good till i drop it into drive. still need to tweak it, but i'm gettin closer.
