Right now I have an F22A6 with an H23 plenum and TB. Unfortunately, the guy who sent me the whole thing didn't tell me there were some broken and sealed off nipples. In any case right now the #21 nipple is broken off and sealed over w/JB Weld, and since I have no A/C I have the #21 line going off the EVAP nipple that would go for #20. The car runs OK, but at idle the throttle sticks, and when you give it a little gas the car surges to 1500RPM.

Anyways it looks like I'll have to either get a new TB or yoink and replace that OG MAP sensor nipple. Is it possible to replace a nipple or do I need a new TB?
