Good morning,

ive done some seraches and think ive narrowed it down its at the shop now just waiting to be looked at but i still value what others have to say.
2010 camaro 3.6 95,423 comes up misfire cylinder 2 changed all 6 plugs twice as well as coil and still misfire and runs rough im thinking injector but im curious what others think. The P2303 Ignition Coil B Primary Control Circuit Low
code is what throws me off.

update 1st shop i took it to (where warranty company told me to take it)could not figure it they said take it to the dealer as its in the electrical harness as the code keeps pointing to cylinder 2 i was like really did you test injectors answer was nope. So warranty company approved dealer so thats where it is at now....

No reason the expect the injectors. If the code you gave is correct, it's telling you the voltage is not being supplied to the coil, so likely a wiring or fuse problem.

You were 100 percent correct there was a break in the harness that fed coil 2. The dealer is doing the repair all covered under warranty
