Default P0302 and nothing is fixing it.

Okay so
i ended up getting a bad sputter and misfire in cylinder two (P0302) and changed out the spark plug and coil in the correct one. I still have the misfire and want to confirm it may be the Injectors. Anyone think different?
Damn this evil glorified VW (but i love it still).

Very possible. You try Seafoam in the gas?

I have not done the seafoam in the gas as of yet but will probably pick some up tomorrow. The spark gaps are correct and i have yet to check the wiring, i will definitely jump on that tomorrow. Thank you

Changed teh plugs again and still chugging,Also got 2 new coils for both center cylinders and nothing. I cleaned all connections and did not notice a change even when i disconnected the cylinder 2 injector it also did nothing but i can hear it firing up. I noticed a vast amount of condensation coming out of my exhaust and a bubbly sound while driving .

The other night i got the same thing and ran it one the highway, the cel would blink for about 15 or so seconds and hold for a few more and repeated itself for a few minutes until it completely stopped and the car ran great. started it back up next morning and chugging with the code.

i ordered an ICM just to be safe , the wiring seemed fine from what i could see so i am at a loss.

I would try swapping injectors before throwing more parts at your car but that is me. It is possible the icm is bad. It is also possible you could have a bad injector.
One more thing to remember is that your ecm will shut down fuel to a cylinder that is misfiring so it is important to reset fault codes when swaping parts.
