Installed the Delteq about a year ago, never ran perfect, but pretty smooth. A month ago it started getting real rough, changed the Autolite 106s and found all to be soaked rich, but #4 was gapped tight and spotless. Installed some 104s to go a step colder due to the heads/cam and gapped at .038". Also replaced the Delteq wires with some Accels, still very rough in open or closed loop. The blms are split 121/149 at idle, and it reads lean when driving through different fuel cells. Pulls 8*timing at random (has been doing this before the problem). Valve adjustment is decent, tightened loose bolt on pass. header, cleaned TB and IAC, coils spark when tested, no codes, and still no change. I have a few scans I could send anyone if they got the time, but I'm getting lost and don't feel like dumping money on a bunch of parts that won't fix the problem
