- power professional 65mm throttle body
- about 3000k's on the new throttle body
- started to happen in the last couple days

seems to only stick on the initial push, otherwise it's fine for the rest of the travel
the real kicker is this only happens with the car running, with the car off it's smooth from start to finish
it's as if the vacuum is strong enough to stop the butterfly from moving when closed but once open it'll be fine

checked the throttle cable and it seems to be tensioned enough and nothing seems loose/caught

anyone have any thoughts and/or ideas on my problem?
