When you re installed the fuel injectors, did you use new o-rings and seals? There are o-rings that seal the injector to the fuel rail, and rubber seals that seal the intake manifold to the injectors. If you haven't done this you could have a vacuum leak and/or small fuel leak. You should replace these if you didn't already.

I took my fuel rail off just to clean my EGR passages one day. Upon re installing everything, my car would not idle and ran rough. Turns out even though the seals looked fine, I need to replace them. They cost < $10 OEM from Honda and fixed the vacuum leak.
