MAF and egr codes

my truck has been running bad and i've had two different readers read it and got two different answers one was something to do with egr pressure being off and the other was the MAF. What are some signs of a egr going bad.

P.S. i've already cleaned my MAF sensor and i've also seen a decrease in gas mileage.

Thanks

replace both the egr and maf. Use stock egr. and switch to 10w30 motor oil. you should get anywhere from 18 to 22 mpgs.
