I had same probs with my 20 v I did the egr valve which was abit sooted up and even after putting a new maf on didn't correct it , so after checking on here a fella had the same problem ! It then turned out to be a split pipe which is on the top left on the radiator it goes to a turbo boost valve , the pipe is about the same size as a windscreen washer hose pull it off and give it a good check over . This was the problem mine had I couldn't believe this caused me so much money and time and was fixed with a pipe I had laying around in my garage.
