check your AFC wiring?

Did you cut your O2 instead of your MAP sensor input?

No wires are left unatached. I have an a/f gauge & it works. So do the r.p.m s on the vafc & I also have Vtech set at 4400 & it kicks in at 4400 . It's night time now, I'll check it out further during the day tommorow. Thanks, & if anyone else has a reply, please post it. This is my first vafc install & I welcome any help. Thanks in advance.
