It's better if you run a leak test w/o the car running so you can hear them. Search 'vac leak test' there should be a write up or two out there it's fairly common it the turbo world.

Check the connections for your mass airflow sensor. If its all connected and fine then Get the error codes from your car. You might need to get a new MAF.

Go to autozone and have the codes pulled and post them back here.

Try swapping the coil with another to see if the problem moves. If not, do the same with the spark plugs.

a couple of choices here P0302 = misfire detected on cylinder 2 problems could be engine mechanical fault, ignition/fuel system, injector leaking, ECT/MAF sensor, ECM im going for the coil pack
