DBW failure Got a cool new problem. Starts up and idles then after a min idle creeps up to 2100 rpm and my gas pedal stops working. No CEL no codes. Reflash same tune and its back to normal for a test drive then does it again. Anyone been thru this before? I am guess ing it is just going into limp mode but why? No codes to tell me anything..

My only guess is that there's a vacuum leak, and a big one. But diagnosing over the internet is hard.
Data logging would help. AFR, MAF, desired idle air, ignition advance, throttle blade angle, pedal position, RPM... not sure what else, but that will probably do.
