Message But it may be coating your MAF sensor.

That would probably cause it to think its getting more air than it actually is. It would supply more fuel and you would be running rich (describes your symptoms)

You should try cleaning the MAF (be careful its delicate) with some MAF safe cleaner.

If that doesn't help (it probably will) then its possible your O2 sensors need to be replaced, that's a fun job. (Theyre located on the exhaust, look on either side of your engine up against the firewall)
