Mitsubishi Repair: check engine light, mass air flow sensor, mass air flow

Question
changed 02 sensor and mass air flow sensor as recommended by diagnostics. light remains on, what else could cause tjis

Answer
Andy,
There are several sensors and emissions components that can cause the check engine light to come on.  If you could reset the light and retrieve the codes again, it may show new codes.  Places like AutoZone can scan and retrieve those codes for free.  They can also help recommend the possible cause and fix.
Good luck!
