This morning I went out and started my 2008 tahoe and I noticed the idle was shaky and the exhaust didnt sound right maybe because it was misfiring. So i went in grabbed my scanner and Im getting a P0171 / P0174. I have checked the intake for any lose hoses but I do not see anything. I checked the misfire log and seen that cylinders 2,6,and 8 were randomly misfiring. Anyone have an idea on how to troubleshoot this??
