Best answer

21000. A diagnostic trouble code should stat out as "P" code which stand for Powertrain. ex, P0XX, P1XX, P2XX. General error is not a trouble code. Make a inspection of the MAF (mass airflow) air duct tube for proper connection A MAF that does not calculate the proper air intake can do this. Chevrolet Express Engine Components
