I had my stock LS1 TB ported and polished. When I put in on my car it sticks before it opens but once it is open it is fine. How do I fix the sticking or is it no good?

Usually when that happens it is just dirty where the blade contacts the housing, but if it just got ported sounds like they may have messed up the opening, another thing is if the stop screw got messed with it may need to be adjusted out ( I cant remember for sure if the LS1 has a stop screw for sure )

If the throttle blade was knife edged it will feel really sticky apon first opening from a standstill.

probably not centered in the housing and getting hung up. try adjusting it

it only has to be off a bit for it to stick . before putting the blade back on it is good to make sure the shaft is in good . maybe tap on it with a rubber hammer to make sure it is all the way through .
if you still have problems look st the throttle body and see where it is sticking or rubbing . then take a sander roll and just remove a small bit of material till it does not rub .
