That could be a lot of things...
Please help us help you and tell us what you have done.
I would:
- Clean out idle speed control valve. I might also unplug it while idling to see if there is any change.
- Start it with MAF unplugged to see if that changes anything. If it does, I would do a proper smoke test (no cigar) and look for vacuum leaks.
- look at long-term fuel trims for a rich or lean coonditon.
