The error message on check engine light shows too rich on fuel after I replaced the 2 fuel injectors. Is it possible to calibrate or adjust the fuel/air ratio so my RAM B-250 able to pass 'the test' only smog testing.

Hi:
There are no adjustments. Everything is done by sensors. Make sure the O2 sensor is working.
