The evap system hooks to the plenum just beyond the TB, it runs into the same connector that the AOS breather connects to. It has nothing to do with any of the vac lines that he has pictured so far.
STL is right, some euro cars (Germany and GB) have the SAI system just like ours. There are several different versions of emissions tunes for Europe. Only true ROW cars (sold in middle east for example) did not have the SAI system.
ColaCharlie - do yourself a favor here. There is a diagram of your vac system in the trunk. The line that comes off of one of the bank 1 (passenger side) boots either on the plenum or resonance tube, has become dislodged. As I said earlier, it is the tubing that goes to the SAI and resonance flapper actuator, along with the vac reservoir. Study the diagram, find pics of how everything should be connected (Stl has a nice pic on the post he suggested you read) and hook your stuff up properly. Then see what happens.
This isn't rocket science. You have a vac leak on bank 1. You are leaning out and detonating (not misfiring, big difference) on bank 1. It is happening at WOT because your fuel trims can adjust for the leak while under closed loop operations. When it goes open loop (i.e. WOT) you lean out and throw the code. If you don't believe me, buy a $15 elm327 tester and download your long term fuel trim data. $5 says that your bank 1 is going to be positive and much higher than bank 2 which should be close to zero or at least very low positive single digits.
