Hello, the motor is the 3.4. I brought it to the dealer and had the mass air control unit replaced, might be the wrong words, and I replaced the idle air control valve myself.

What its doing is, when driving slower speeds through town, and taking my foot off the gas, the car will stall, it will start right back up, but I have to put my foot down on the gas some to get it going. If I can see its going to stall, I pump my foot down on the gas pedal a few times and it revs back up. When at highway speeds, it will stay running. Also, when I stop the car and put it in park, it will just shut off there as well. The check engine light is off also.

Any help will be greatly appreciated.

Hi, thanks for the donation. How long since a tune-up? You may need to take the throttle-body off and clean it, if you haven't already. I always check for codes, even if the lite isn't on, just a habit for me, only takes a couple seconds.

I've owned it for 2 years now and haven't had a tuneup on it yet. I did replace the fuel filter and the tps today. I will have to try the cleaning the throttle body like you said.
