Hey Keith,
This might not be your problem but I think it actually helped smooth out my engine on cold starts: I had a fault code for my MAF sensor, so I replaced it. My car ran much more smoothly this morning than it usually does. I'd imagine if this was the case for you, you'd have a fault code as well. Might be worth keeping in mind while you're troubleshooting. Here's the old MAF (dirty, left) and new one (clean, right)

We can't just use any type of solvent to clean the MAF Sensor. Here are a couple of very important guidelines on what to use:
CRC MAF Sensor Cleaning Spray
This cleaner is made by CRC Industries and its part number is: 05110.
You can buy it at your local autoparts store (Autozone, Pepboys, O'Reilly, etc).
Don't use carburator or brake clean spray or gasoline.
These solvents will leave a residue on the wires.
Not to mention the harsh solvent can damage the MAF Sensor's electronics.
Also, don't attempt to physically clean the sensor with anything (like a cotton swab) or you may break the wires.

I think if you are careful, you can spray a solvent on the "Dirty MAF" and then blow it off with low pressure air to clean it. That should make it "work like new" again.
