Question Sticky LPE TB?

Minor issue with the LT-1 in my Corvette. I have a LPE throttle body and now that has gotten hot and humid I think something's hanging up in the system. When I stop, shift into neutral (M6 car), and let the clutch up the idle want's to hold at about 1100-1200 RPM instead of it's usual 800-900 RPM. Is this electronic or mechanical glitching? What's the best way to figure it out and fix it?

TIA!

I got a bbk tb on my lt1 and its doing the same thing started recently since the warmer weather. Havent really looked into it but figured out when you come to a stop tap the gas and it should idle down. this is my temporary fix.

Thanks - no dice on the "tap fix" (but is does sound cool at the stop light...you get these moms in minivans thinking you want to race... ) Hmm...

BTW the reason I said check the cable is some times they get moved and get tenion on them...just ever so slightly holding the throttle open. I had a few cars get me on this before I started checking them first thing every time
