Post a clear picture of you engine bay.
Your signature states that you have a tune using HP Tuners. Who tuned it? Can you post the tune?
I paid a guy to tune out the DOD and he uploaded a tune via HPTuners...so i would need to ask him to send me the file. Honestly, the car pulls fine and drives ok, but after the tune the idle was a bit higher than normal and then 2 months later this code starting coming up. I am almost 90% sure that this is tune related. Even the transmission shift points are off and i think the tune he uploaded upped the pressure line on the tranny so it jerks every gears pretty bad. I will post a pic of the engine bay as soon as i am out of work. Meanwhile let me see if I can get the tune emailed to me
