04 suburban, having random P0171 code and missfire
Good morning!!! Hey guys I am scratching my head on this one. I am getting a P0171 bank 1 and when it does it i get a missfire. It does not do it all the time. Does not happen whenever it first starts, just whenever I have driven it a good 30 miles or so. It may not do it every time either...- Shatcher0428
