Yeah, replacing the injector was a bone-headed move. I even checked them with a flat head screwdriver and they were all ticking away normally. I was pulling straws at that point though. I did try to swap the AFM for another one, but I wasn't sure of the replacment's condition and the miss didn't go away, so I put the original back in and didn't touch it after that.

I have another complete 22re engine in my shed so replacing the injector didn't cost me any $, just time and headache <img src="/forums/images/graemlins/smile.gif" alt="" />.

I'll hit the boneyard tomorrow and try to find another AFM if the cleaning doesn't work. I'd be surprised to have two bad units though.
