Default Rich and three misfires! UPDATE 8/9/14

UPDATE: see post #4

Just bought a Tactrix Cable to try to fix my car, but looking for some NASIOC guidance to make sure I'm on the right track!

I'm thinking boost leak, change plugs, and coil packs?

p0172 - System Too Rich
p0301 - Misfire Cylinder 1
p0303 - Misfire Cylinder 3
p0304 - Misfire Cylinder 4

Magnaflow exhaust
Perrin crank pulley
Cobb SF intake/box
FMS top mounted intercooler
Dyno tuned @ Bren Tuning

When boost kicks in/2500+ RPMS car shakes a lot (misfiring). Low RPM's the car is fine. The car has stalled out with clutch in, which is definitely a sign of a leak. Going to smoke test it and fix the boost leaks, then see what happens. I can try logging it and post the results if you guys need it.

Check for leaks, tighten everything down good. The smallest leak can cause this type of problem.
If that doesn't fix the problem, change plugs, make sure to gap them correctly.
Goodluck!

Have a boost leak test done after that the next option would be replacing spark plugs if you haven't already done so.

Did the trick with soap and water. The only spot that bubbled was the part circled in the photo (from the passenger side, bellow the intercoolor, connecting to the turbo, towards the front of the car). So... tighten down that clamp and hope it fixes it? If not, new plugs, then new coil packs?

Sounds like a good plan. Try that and report back!

Leaking between the turbo and compressor I guess... Maybe time for a vf52? lol, car still can't breath. Snapped about 10 bolts from removing the heat shield and tightening that clamp. Haven't been driving it so I think I'm going to just drop it off at Bren to take care of it.

Actually just saw the same thing on a GTI we have here at the shop. Sounded horrid, found the exhaust part of the compressor had blown the pipe off the exhaust flange where that clamp is. Pretty odd for sure
