Default High/Bad idle issues - codes read MAF - Still Bad idle

Have had awful idling issues, had my codes read and they told me it was the MAF sensor causing the issue. I bought a new MAF sensor and replaced it, check engine light is off now (after disconnecting battery to replace sensor) and I have not driven it yet to see if it comes back on. Thought I am still having idling issues.

I do not see any obvious vacuum leaks.

Just wondering if anyone had any suggestions on what it may be, considering the codes read MAF, if there is anything that may be setting that off that is not the MAF.

Also, turning on the AC or just any air at all usually takes it down from 2-3000+ RPMS down to 1-2000RPMS. Not sure if that has anything to do with where a leak may be or what may be causing the issue.

After replacing your MAF, have you had a code check? Yes - No ? Any codes still there?
