If it were an intake leak, I'd expect it to also trigger codes 1128 and 1130, which indicate a lean condition at idle. In my case, a small leak ONLY triggered 1128 and 1130. A defective or dirty MAF could send erroneous signals to the DME (ECU), telling it to lean out the mixture. There is a post on Rennlist indicating that in one case, changing the MAF did, in fact, solve this issue. Google "Porsche", "P1126" and "P1133".
