What’s the misfire code on my Chevy Silverado?
After 137000 miles, I got luck and had no AFM issues until now as my 2009 Sierra is throwing a misfire code for cylinder #7 (P0307). I swapped the coil/wire/plug with cylinder #3 and the fault followed, so I swapped the coil back to it’s original #7 spot (plug wire got broke, so it’s new) and the fault stayed with #3.
