The car stutters and almost falls flat on its face whenever I start it when it's cold. It only happens when I lightly touch the throttle. It's less obvious if I rev it a little more, but it's still there. When the car is warmed up, it's not as bad, but the problem still exists. If I unplug the AFM, the cars idle stays the same unless I touch the throttle again, then the car just about dies. When the car is completely warmed up, and I unplug it, the car dies. I was unable to unplug the DME temp sensor, but I will attempt that another day and see what happens. I did not want to rev the car hard since it was not warmed up all the way.
