Have someone check the idle sensor. I had to have mine replaced along with another that I don't remember which one is was.

Sounds like your water pump is going out or your thermostat is stuck. Check the thermostat first and make sure it is not frozen in the clsed position.

On modern day cars the parts that get fitted need to be adapted to the ECM using a decent diagnostic machine. I bet that this was not done and the car is now suffering as a result.
Something to try is resetting the ECU, simply disconnect battery for 10 minutes, reconnect, then start car from cold *without touching gas pedal* and leave idling until the rad fan comes on (this resets all the base idle settings) then take it for a drive - hopefully will solve the problem

check egr valve for vacuum leak. pull hose from manifold. put hose in your mouth like a straw and **** on it. if the valve moves, then it's good. if it doesn't, you need a new egr valve. WARNING, they are fricking expensive! auto zone price $204. NO JOKE
