I don't know the answer but i have the same problem. I have cleaned all the egr system, changed the throttle body gasket, changed plugs, wires, cap and rotor button. I still havent got it fixed. There is a vacuum motor on the very back of the motor, behind the bpt valve, and I'm curious as to if it could be the problem. If anyone has the answer, PLEASE, type it. This has really got me confused to what it could be.
