2003 Ford Explorer AWD XLT 4.6L STICKING THROTTLE

[Bar1]

Hello,
I need some help with an issue i am having with a sticking throttle. I have replaced my IAC and TPC. Replacing my IAC fixed majority of my Idle issues I was previously having but now while I drive and try to stop my throttle sticks at around 1500 and 2000 RPM. In order to get the throttle down I need to put it in Neutral and wait a couple seconds and then it kicks down.

I have also Cleaned th MAF sensor...no change.

What else should I be looking at? Might I have something clogged up past the throttle body around where the IAC is connected? Can a Vaccuum leak do this?

Any advice or suggestions would be greatly appreciated.
