Clean out the throttle body, you can do it yourself in about 15 minutes. Take air cleaner off, spray throttle body cleaner in, whip out with clean cloth around the edges and your ready to go. I had to pay a dealer 150 bucks to do this and when I did it myself I was ashamed that I payed anyone to do it. Just bought another one, I have a 2005 and 2006.
