Hello,

I have a 2011 Chevy Tahoe LT. I'm getting these 2 codes P0171 and P0174. Bank 1 and Bank 2 running tot lean. What can I do to fix this problem. Also my heater is not working?

Thanks,

also define heater not working? as in no air blowing or only cold air blowing?
what does the temp gauge read?
could be related to lean code..
