The throttle body is often the culprit , cleaning may help , but replacement can only make the car run better .
The v6 has a metal oil trap that has a small hose outlet where the small hose going to the throttle body has inline a one way PCV valve p/n 9189564 . That little valve can cause most of the symptoms . There's a metal unit for replacement as well as plastic . It is also common that the tiny hole at the brass fitting on top of the oil trap gets plugged . Clear it out with a small drill bit .
Also the larger rubber hose elbow at the oil trap can get loose with age . p/n 4527222
There's also the fuel filter , but seldom the main problem maker .
Good Luck !
