I have an 05 silverado with the 6.0 and every once and awhile i get a misfire when at idle at a stop light, but just recently it got worse to when i wanted to go it would sputter and that only happened once but i still get that small misfire i have 87000 miles on it and no engine codes please help me thanks
Have it checked with a diagnostic scanner. The scanner will show the misfire history and let you know which cylinder is misfiring. That would narrow your search to finding a fix.
