I have a 2002 Camaro with 73500 miles. Recently the service engine soon light came on. I have a handheld diagnostic reader and it states lean bank 1 and lean bank 2. What are the possible causes for this? Could it be the mass air flow sensor or 02 sensor?

Thats the o2 sensor giving you that reading. You could replace the o2 sensor or try cleaning the old one. Look at the bright side. Running lean saves gas lol.
