Are you pulling it off the 90' or 94'?
The 90' TB has a coolant line attached to the bottom that a lot of people overlook. My TB slides off, not easilly, but have to pull the coolant line, TPS plug in, IAC plug in, throttle linkage, and I beleive the filler CAP. If you forgot that coolant line, it MAY be hanging up on that as it is VERY short. I know I can get my TB off without pulling the filler TUBE. It is a stock TB on mine though.
Dont wiggle that tube too much or you be pulling the valve cover off to do gaskets next. Got to be someone on here who knows a trick on getting that tube off..
