If your Egr is stuck open at idle then that would explain your crappy idle. Egr is used at cruise speeds like on the highway mostly. When the engine is cold it richens up the Afr allot, so theoretically if the egr is stuck open wide and your engine is cold it will let allot of exhaust back into the cylinders which will displace oxygen and cause the rich fuel mixture to not ignight.

Try swapping the egr's from car to car.
