Check your plugs, if they are all the same color, your injectors are probably fine, so you can rule them out again.
I did all the work, i double checked the values on the injectors and i will check again today. but I'm 99.9% sure they are coded and installed right everything is torqed to spec, and the plugs are new lol the car is literally 1 day old of a 3 month coma.. i was expecting a new car that just rolled out of the dealer haha i should have took the block off and got it bored. and ported the head.. LOL to rule out everything.
