The idle droped when i had disconnected it on the old one i had on there.but my idle was weird.So i put another one on there and dissconected it and no change in idle what so ever. So i put the old one back on and still no change in idle at all either.Im stumped.

With the gas pedal hanging, that is probably something to do with the linkage. Clean up around TB and linkage.

binding of throttle linkage. or in my case i had this build up around the opening of the TB butterfly cleaned that out and it helped alot, almost clear it up completely.
