Replaced Air Filter and now she idles badly and stalls

[kk2002s]

My car came with a K&N, I have done the normal clean and re-oil a couple times with no detrimental effects. I started getting the hunting idle.
I did a complete Throttle body, tubes, MAF (Use MAF cleaner) and now my idle is rock steady
I had switched to a K&N on my mustang and was concerned about the MAF getting fouled but it never effected it

I think you need to see what residue maybe lurking in your throttle body and using some MAF cleaner.
