I thought about the mass air flow sensor but the computer is no kicking on the SES light so it can't be the MAFS, because it should kick out a code right? I am not getting any code and yet it has a terrible miss like a plug is fouled so I am taking those all out today.

Just make sure, before you spend any money, that you double check your harness and the plugs for both the coils and injectors. Take them off, make sure they're clean... maybe a little wd-40 on the connectors and plugs and put them all back on. Try jiggling when it's running to see if the miss goes away. I only say this because I had an issue with the injector harness at the back of the left bank one time and jiggling made it go away... cleaned it out with some wd-40 and it's been fine since.

I didn't get a code for my miss either.
