I don't know what should be done. I changed O2 censors in my system. The Check Engine light on dashboard came back. I came to the service to read the computer again and it says - Code: 16785 - Exhaust recirculation flow too low. Does anybody know what this about? What should be done now? I hate this Check Engine light. It seems to me it is going to be forever.

Any ideas are highly appreciated.
Thanks.

SEARCH EGR VALVE- THERE IS A LENGTHY PROCESS THAT I HAVE TO DO TOO-(sorry about caps all fixed) there is also a check for the valve itself (apply suction to one side and see if engine rpm drops) The longer fix requires cleaning carbon from somewhere- sorry i cant remember specifice- Again search EGR...maybe someone has the link!!try EGR, cleaning egr, cleaning intake , check engine egr.

In addition to what Rick 601 says, check for a kinked and/or disconnected vac hose

Sorry for asking, but I'd like to verify what is exactly mean "EGR".
Thanks again.
