Default what could be the problem, DPFI ---> mpfi

okay, this is my second time doing this conversion and the first time came out like a champ. i had better info then, then i did now. i sorta guessed about what im doing this second time. i swear i did everything correctly as shown on http://www.fourthgenhatch.com/mpfi.html
here is the problem i am getting.
code 4 and the car hesitates really bad at 1500 rpm's. EACV is making a weird squeeling noise. i moved b2-->b10 but i didnt move b11--->b12 because i had a wire in b12 already. this was stated in the above link. let me know if there is anything here that is useful.
p.s.
does anyone have the dpfi-->mpfi from sport compact car, or was it import tuner, or some other magazine from about a year or two ago. i need that article. i swear it will answer the questions i have.

I have used these instructions for several DPFI to MPFI conversions and they work great:

one thing that guide you used doesn't tell you is that when you cut C1 & C2 (orange & white) you need to connect wires that originally went to C1 to B10 and C2 to B12
