I did my H22 swap last year and since then I have been coming up with multiple problems. I always had the hesitation, but got to do it not as bad, plus I would throw the CEL for knock sensor while cursing on the highway. Last week I got a VAFC II and yesterday I had my car dyno tuned. It is like driving a totally different car now. It doesn't hesitate at all (pulls nicely) in the mid-range, and no sight of a CEL. I need to go to the track asap. Add .orig.jpg for full size.
