I know this code is very common, I have an 06 Cobalt SS/SC. Ive seen spark plugs, coil packs, injectors. Which of these is it!?

 

Typically caused by injectors, I get this code with my Siemens 60#

 

When is it misfiring? Idle wot decel? I would check the injector insulators if you've replaced injectors as well as have your tune looked at if it's through hp. I just went through that code and it ended up that my tune needed to be treated slightly. I couldn't even tell the car was missing but it was only on decel.

 

Usually injectors but doesn't seem to be nearly as common with hpt. It's almost a guarantee if running a trifecta tune
