I installed a Novi 1000 over the winter and now I'm having some problems with the idle. The car will idle for a few seconds (~20) and then the idle gets really rough and the car stalls out. The same thing happens while driving...it'll stall when coming to a stop. I've checked the vacuum system (pulls 19-20 at idle) and there are no leaks, changed the O2 sensors, new plugs, wires, etc. My plugs are Autolite 23's gapped at .035. Any suggestions on what is causing this problem? I've tried all kinds of fuel pressure settings, from 35 psi to 45 psi and it doens't change the idle/driving characteristics. What else could be causing this erratic idle?
