Oh, not that kind of problem. Sorry.
Basically, what Gerhard said. It's probably ignition, but there are cheaper solutions than a new DI to try first.
Get the NGK's specified in the manual. The exact ones, not some cross-referenced Champions or Blastfires the guy at the parts counter is pushing. The DI is VERY sensitive to spark plug type - now is not the time to be messing about. Next, check the gap on each one, and again set it to the value in the manual/on the decal in the engine compartment. Spark plug gap is critical in a turbo - too big, and you get misfiring at boost. Never assume a plug comes out of the box with the right gap for your car.
OK, if that doesn't do the trick, pull the DI cassette and flip it over. Yes, there is probably oil in the 'well' between the cams, but chances are that's from a leaky valve cover gasket. With the DI cassette on its back, you'll see 5 or 6 torx screws holding the plastic cover on. Remove the screws, and pull the cover off. You'll see the 4 DI coils. Flip the DI cassette back upright, and peer through the translucent white plastic of the coils. Each should be about 80% full. If one or more is down on oil, or any of the plasic coils are cracked and leaking, you need a new DI. Look at the circuit board for signs of burnt components.
The DI may look fine and still need replacement, but if it looks bad, then you KNOW it needs replacement.
Hope this helps.
