That's a tough one. It can be dozens of things. Generic code readers do not help much. It will need a better one to try and isolate the problem. I would start by torque the intake manifold. Its a known source and easy to do the bolts just need to be snug . 10 mm and a swivel helps get them all checked. Then looking for vacuum leaks would be next. Coils go bad but can be isolated by unplugging one at a time to see if the car runs worse.
