I knew the recommendation was always to replace IP and injectors as a matched set but I thought I might get away with breaking the rule here. I think I'll just run extra additive for a while and see if things clear up anymore. Cash is a little tight to be buying a new IP and sticks since the ones I have are working other than a slight knock at cold start. Redline 85+ and Optilube XPD did make a huge difference in just one application.
