Default Idling high after startup

Long story short, the other day I opened up the hole in my throttle body to 1/4" up from 3/16" (it was being pissy coming down off throttle after cam install). I also used MAF cleaner to spray out my MAF. Now for the first two minutes or so after startup, she wants to idle at 2k. any ideas? also recently ive been throwing a code for one of my o2's (P1153 i believe) but it was running fine before i had to go and **** with the tb/maf...

yup that will happen if you drill it out too much. Use HP tuners to scale back the IAC to try to correct the idle.

If you dont have access to a tuner then buy a new throttle blade.

You can custom tune the idle down, or do what i did before i had tuning software, Is to epoxy the TB blade and redrill it. Go to the tuning section thats were you can find the most help with this issue

Liquid Weld works great for plugging the hole.
