1994 Chevy k1500 code 44 problem

[Tanner]

Alright so I just recently got a code 44 on my 1994 Chevy k1500 the check engine light turns on after driving for a little bit, but the truck drives fine the only thing I notice is it getting too much fuel and black stuff coming out of the exhaust when I first start it. I did some research and replaced the Egr valve and solenoid and cleared my codes but it showed back up that night.. What could be the problem?

I think code 44 is o2 sensor and or a vacuum leak. Usually a lean condition though I thought.

Thanks for your help! It ended up being both my o2 sensor was bad and I had a vacume leak on my pcv valve line.
