Too rich fuel

[Dubwatson86]

My 2014 Silverado says my fuel is too rich and it smokes blue fromy exhaust. How can I fix this?

Codes will have to be diagnosed at a good repair shop or the local dealer to start. Or, you can research the code yourself online and try and fix it yourself if your mechanically minded at all.

First, scan for codes.

 

Second.  pull your dipstick and see if your oil level is overfilled, or if you get a strong smell of gasoline.
