94'wheeler

Story goes like this: Replaced fuel injectors recently with some rebuilt ones. Pulled the air intake chamber off, left the manifold on, and didnt even remove the fuel rail fully. Put everything back together with new gaskets, even throttle body got a gasket. Hooked up vacuum lines, checked them 3-4times. Engine starts and idles very rough, lots of shaking goin on. Exhaust certainly smells far richer than normal. Anyone have any ideas on what I should be looking for?! I'm thinking about cleaning the MAF, maybe thats a place to start!? Thanks in advance!
