P1175 chevy express 3500 2008 is showing me this code

Question

2008 chevy express cutaway is giving me p1175 code. what is the fix please. thanks

Answer 1

P1175  Fuel trim cylinder balance

Any misfire code condition with this code? This code is mostly accompanied by a misfiring cylinder, a good look into the sparkplug condition helps isolate the cause for this code to set.
