How to fix rough idling engine?

My motor idles at 900rpm but is really rich and ugly sounding....it just has trouble and dies sometimes....is there anyway to fix this easily? I have checked TPS and it was right on?

Thank you,

Meatwad

Check O2 sensor and spark plugs. They should give you a clue.

Did you set minimum airflow? I did this on my car with an idle problem and it helped. Also the IAC is worth checking out as well.
