running rich and smells really rich at times

You didn't mention if you have an adjustable or stock fuel pressure regulator, but check around there for leaks too, then it's time to consider a leaky injector. Were the injectors new when you bought them or used?
Then it's sensor check time, o2's and EGR...

You might also want to check the charcoal canister filter vacuum lines/hose, if they are broken or disconnected, the fuel fumes are noticeable. Also check the injectors to verify none is leaking as Hozer 88GTConv suggested. GL
