your evap has no correlation to your maf. Any mods to the car? When was the last time you cleaned your maf sensor?

you have a fuel system issue, with the evap canister system for the fuel tank

Are you sure you just don't have a bad gas tank cap. I know if its loose or not sealing correctly it will throw that code. A bad or dirty MAF usually causes motor surging and Idle problems on my car.

From my manual:
P0102= Mass air flow sensor circuit, low input
P0157= O2 sensor curcuit, low voltage post converter right bank..

P0102 is the the code that needs to be addressed first. This is an indication you MAF has failed. Is it a factory MAF or aftermarket?
Check this thread out for P0157:

You can usually do a quick check of the MAF by tapping on the flat portion of the sensor body with a screwdriver while the car is running. If the engine stumbles or stalls, the sensor is faulty.
You can also check voltage with the ignition key turned to the on position, car not running. Check the voltage on terminal B ground (black/white) and terminal A (yellow). There should be between 4-6 volts .
Last, you can check the battery voltage to the MAF with the ignition key turned to the on position, car not running across terminals B ground (black/white) and terminal C (pink). Should read 12 volts.
This is from the Haynes manual for pre-1998 V8's.
