Idling issues...

I checked my codes and can't remember the number but it said I could have a bad maf, o2 sensor, or a misfire. My car is idling high at 1500-2500. Sometimes its normal but mostly stays high. I replaced my maf and wouldn't think my o2 sensors would cause this? Could I have a vacuum leak. Sometimes it will also ping.

So far I have replaced my iac, tps, maf, and removed my chip to see if the problem still occurred. Well....it did I sprayed the hell out of my engine bay with carb cleaner looking for a leak but my rpms never rose. My t-body screw is backed off where it isn't even touching the butterfly. I have my intake completely off and decided to stop for the night. When I put my new one on tomorrow hopefully my problem will stop. I did notice that the t-body I am installing has two small holes in the butterfly valve?
