2006.3500 2006 3500 6.0 multiple miss

All new coil packs and new fuel injectors and still a multiple cylinder miss...?

Use a scan tool to watch live data, see what cylinders are misfiring.

 

P0300 code just means more than one cylinder.

 

If you just shot gunned those parts in without proper diag, that will kinda suck because all it did was cost you money.

 

You could have other issues, like poor compression, broken valve springs, poor fuel pressure or some other sensor causing it to misfire.
