Quit making fun of me
I do think though that the Vac can affect things, as when you pull the Vac line things get a bit nutz. But maybe not so much shift timing. I got that 85 CA vac system PEGGED though.
How do you switch out the kickdown switch? Just a couple o' nutz or is it a twisty of sorts. Be nice to have an idea before I go crawling around in the slush.
