Mine does 33/35 local and around 40/42 on a speed legal run.  Faulty egr would bring on engine management light.  Probably mass airflow meter as this does not bring on light.  Try unplugging it to see if it runs any better.  If it does, the maf is faulty :y

Gummed up swirl flaps will also cause this.
