Scoped the MAF sensor using Pico's new frequency software and can see nothing out of the way with the swirl flaps control vac pipe disconnected. Car drives fine like this and is not logging any DTC's. Not having stripped one of these manifolds does the flaps control long and short intake routes, because closing the flaps seems to strangle the engine on anything but tick-over I'm thinking that the ECU needs re-flashing.
