Flushed your rad for your A/F being rich? Could be the MAF, you could try cleaning that. Hopefully someone with a shop manual can chime in.

MAFMass Air Fuel sensor. It's located in the tube of your air intake little black thing that is held in by two screws. Disconnect your battery, remove the sensor, clean with MAF cleaner, Put sensor back in intake. Reconnect your battery.
