high idle

    1998 "W" S-10 4.3L 5spd RWD 144k Miles I'm out of ideas with that TB, read a lot about them but the topic never had the solution at the end... Idling fine when the truck is not moving. (has a slight misfire only at idle and some backfire at back shifting but had it before the problem started)...
