try changing your oxygen sensor.

i have the same problem. and i get a code 13 too, which is the oxygen sensor. i havent changed it yet cuz somebody told me it was like $120. i havent looked into it yet, but does that sound right? and would changing it help any on the car stuttering? i dont know my exact fuel milage, but i put about $40 a week in mine, and the only place i really go is to my gfs house everyday (about 15 mins away), and to work (2 mins). is it just me or does that sound like bad gas milage?

A new oxygen sensor only costs between $20 and $55 US. If you're paying more, your getting taken.
