ok we got the su's on the car and we started it a few time and when it got fired up it finally it reved up like it was full throttle , but it wasn't , i checked the buttleflys and they are opening and closing without any probs, is theresomething i could have done when i rebuilt them that would cause this , the linkage I know incorrect but it still sems to operate the trottle correctly, any suggestions

you need to reaset your idler

i think thats what it sounds like to me

yeah i had a similar problem on my Z didn't work it out because I was so worried about it revving up like that.

Could be the idler my butterflies were nearly closed also.

Just incase check for vacumm leaks just a thought.
