Hello room,my o6 trailblazer has these two codes showing p0171,p0496 with the 171 being the first code. they both show up at the same time. I have researched the two possible causes and before I start checking things out my question is could the 0496 code for a evap purge leak set the 0171 lean code "possible vacuum leak" ? thank you don my 2006 trailblazer has the inline 6 and has 140,876 miles on it.the car seems to run fine otherwise
