you say the idle is not smooth, is the ELR working? - ELR is the electronic idle control, there is a connector on the pump near to the manual idle adjust screw, check to see if its connected and if its connected, remove it and verify the engine idles slower.
my car has absolutely zero change in idle speed, no matter if I run the A/C, turn the wheel, have the defrost running - or all at once.
