Help! I've got codes! 565 and 157 Poor gas mileage. :(

Ok, I need some advice. About 700 miles after running the poor girl on the Dyno, I have noticed my MPG has dropped. I finally got a CEL yesterday and pulled the codes today. Codes:

565 - Canister Purge 1 Selenoid/Circuit failure

157 - Mass Airflow is Low or Grounded

My plan is to check the voltage and the wiring to the MAF and locate the Canister Purge 1 Selenoid.

Would the circuit in question (565), lead to the vacuum lines that are located under the throttle body????

Any ideas or comments on how to troubleshoot and fix my baby are appreciated! Thanks!
