Well I was searching around, and I was looking at reasons that my car would "buck" under acceleration. I came across this http://forums.2gnt.com/dcboard.php?az=show_topic&forum=8&topic_id=25719&mesg_id=25719&listing_type=search and it seemed to be the same thing that my car is having. So my question is now.. How do I lean out the fuel for the better efficiency? I dont have the tools or computers at my house. So, if I were to go to a shop, what should I tell them to do? other than the obvious, "hey guys, umm, can you lean out my car?" Also, I know of a shop that specializes in DSM's! One more question, how long would something like this take to treat? I cant go without the car, its my DD! Thanks :-)

Is your car stock? If it is it wouldn't run rich unless there is a mechanical/electrical problem beyond the control of the ECU.

Be careful, running dangerously lean can cause this too. I had a kink in my vacuum hose going to my wastegate which would cause the car to spike to 12-16psi under the pressure inflated the kink. During this instant peak I would register a 21:1 AFR!

Are you turbo'd?

thanks for the quick replies! No my car is not stock, I bought it from fly1 on May 4th 2007. http://forums.2gnt.com/dcboard.php?az=show_topic&forum=16&topic_id=99330&mesg_id=99330&page= . He told me that it ran rich, and that I could get it tuned up though, but its definitely the 625cc injectors.
