Hey guys new to the group I have a few questions hopefully yall can help me . OK so here we go. I have a 2000 Tahoe with the 5.3 I have been getting intermittent rich codes looked at live data maf looks good on look good can'take figure it out went ahead and swapped maf since it was still under warranty. My mpg is around 9.5 to 10 going around 30-40 miles on a 1/4 tank. Idk I'd this is connected but my temp gauge sits just to the left of 180. Live data showed ect was 140. Can anyone give me any insight on this if these are connected and what I can possibly do. Thanks in advance. Bryan

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
