holley idle issues

No mine was OK cold.But when it warmed up the idle was to high.I would readjust the idle and it would be OK.Take it for a drive and the idle would be to high.The throttle looked like it was all the way back,but I took my finger and pushed it back just a hair and it would idle down.So I put a stronger spring and it was OK.If this sounds like what its doing you may try and push the throttle back once its at idle and see what happens.
