Have a 2002 Chevy 2500 HD 4wd auto,50,000. The code is for MASS OR VOLUME AIRFLOW CIRCUIT RANGE/PERFORMANCE PROBLEM. I did install a K & N air intake kit last year. Things to check for or do?

Keep in mind that after a successful repair on this, it will take 3 consecutive ignition cycles and passing tests on this for the light to go off.

Check for any leaks or loose air snorkel connections. You can try cleaning the MAF with electrical cleaner, allowing it to dry completely before re-installing.
