testing @ AutoZone states the code indicates runing too lean front and rear banks? what is the cause and how do i fix it.
you need a real diag from a real shop. could be mass air flow sensor, pcv valve, vacuum leak or low fuel pressure. you can never tell a failed part from a code. it just gives you the system with a failure.
