Sticky CFM 65 throttle body

I have a 2002 Ford Focus ZX3. I bought a 65mm TB but a couple of problems popped up.

1- the throttle is now sticky. Was not doing this with the old TB. Is this a easy fix?

2- I have a short air ram intake and it fit the old TB but with the new larger one it dose not fit. Surprisely the new TB is to small. I am able to tighten the rubber around the TB but do not think this is a permanent fix.

3- also my idle is ruffer now

4- I see people talking about tps when talking about throttle body. What does tps stand for?

Thanks for the help!

TPS stands for Throttle position sensor... Sticky throttle body is in a sticky at the top of this performance page, idle rougher is probably a vacuum leak between the throttle body and the intake manifold... And as far as the intake u proly need a different coupler.. Maybe able to find one at local parts store... All mainly stuff I found on here when doing my homework before buying my throttle body... Have yet to install mine but hoping I don't run into these problems...check out the sticky section for the throttle body... Lots of info in there... Good luck bro...

If the rubber around TB leaks air, an unmetered air leak and your idle issue.

Is the TB clean? How's the idle, may need to adjust the set screw
I now drive a Japanese Ford.
