i am digging through the WDS - i suspect that something is unplugged, or has a poor connection... the onset of the symptoms just does not sit well with me... good thing upallnight pointed to DISA and that issue is resolved... but there is something more there... one of things i thought, that both MAFs, the OE and the aftermarket are not good, but the engine should be running with default values, and it does not... lets see if i WDS has anything to say...
