Update for anyone who has a similar issue:
My car has been tuned with OFT for 2 years now and I just recently cleaned the mass air flow sensor and throttle body for the first time at 71k miles. The car idled high right after first start up and would idle at 2k RPM when slowing down when back into a parking space and using a little throttle. I figured it was just the ECU relearning the idle, so I gave it two weeks to settle. Two weeks came and went with barely any change.
After doing some research and ending up here I made my previous post to see if anyone had any ideas, they didn't. A friend suggested I reflash my tune to stock the put the tune back on. So I gave it a shot and it FIXED the funky idle, now the car pull smoothly and idle normally.
TL;DR: Car with a tune idles high and funky after cleaning MAF and TB, reflashed the tune and problem goes away.
