Okay dsmers, so back when I got in an accident I had to replace the entire front end including the 16g sitting right behind the radiator. After that its been non-stop problems. New FP manifold and Extreme PSI Heatshield, manifold gasket, new ngk spark plugs to spec, new wires, coil packs, radiator, coolant temperature sensor, everything that we could do oem we did and the car drives like a dream. My only issue besides a massive intercooler is whenever I do a cold start the car warms up and idles fine. But if I drive it somewhere turn it off do my thing for awhile and come back, while the engine is still warm I will start it and it will misfire like no other. Sounds like a subaru if you try to drive it. If i let it sit for 5 or so minutes the misfire completely disappears and its fine. Immediatly a code for Cylinder 3 misfire pops up and occasionally the cylinder 3 injector circuit A code along with it. After it stops misfiring the code wont pop up again until the next time i start it after its been sitting warm. Is there any chance my injector is going bad ?? Its always specifically Cylinder 3
 
Interested in what you come up with as mine does the same. I shut it off when hot and start it up and when I try to drive it bucks and kicks but then clears up. Idling you can't tell its going to drive any different.

Sorry I didn’t see this earlier, it turns out I was right and had an injector that was sticking so it had to be replaced, I replaced all ignition components a week prior, coils, spark plugs, wires, so all it left was fuel components. Everythings all good now!
