i put the throttle to the floor and the thing redlined and wouldn't let down so i turned it off and a checked the throttle linkage and it was not stuck. there is a little lever with a notch in it that a peice may have slipped out of. Where the rod pushes down something for it to idle right by the choke. it has been givin me ses lights at cold starts sometimes but i guess it finnally puked. i cant believe it. please help

Regardless of what may be wrong with the vacuum pull-off, secondary air doors, their linkage, whatever, your throttles ARE sticking open. Now, by the time you got the engine shut down, pulled to the side of the road, etc. they had closed themselves again, leading you to believe all was OK. THis often happens on carbs with worn throttle shaft bushings as the they "wedge" in funny ways especially in the presence of manifold vacuum or high air flow through the carb (read: engine running). Shut the engine down and they often work smooth as glass, though. Read my reply in JJ's thread about sticking secondary linkage.
