I cleaned my IAC with a toothbrush and half a can of TB cleaner, it helped.
Then I started to look for vacuum leaks. Check the vacuum tree for missing plugs, make sure the air hose from the air cleaner to the TB is not cracked. Check other vacuum lines for leaks. A vacuum leak will make the engine run very rich.
A poor MAF (mass air flow, measures the amount of air passing through) can cause driveability issues, usually a poor idle.
