Is your car modded or stock, your profile doesn't list much? have you done a boost leak test (BLT)?

Yes sounds bad plugs is what it sounds like. Does the car buck and hesitates too?

I have the same problem, i get sometimes a little sputter or a huge misfire. I have fixed everything in the ignition. If I was you I would do a boost leak test. Im hoping thats my problem.
