2005 Chevy Silverado V8 Four Wheel Drive Automatic
My truck just started to run rough and when I checked the codes, it came up with P0171 and P0300. The scan tool said that the system too lean bank 1 and the random/ multiple cylinder misfire. What could possibly be causing this. Also I noticed black stuff coming out of the exhaust when I last had the truck running. It just started doing this after a recent cold spell.
have the same problem?
