i have a skunk2 manifold with 68mm throttle body. somtimes the throttle sticks, is this a result of the aftermarket (tb)?

 

Skunk2 tb should be recalled due to the bad design.. The cable forces tention on the shaft and causes it to stick.. send it back and get an STR tb.. This is like the 100post Ive read about skunk2 tb issues here and other boards..
