Re: flash codes
where in the country are ya? Dave @ STi Tuning might be able to pick it up for ya. If not then get it towed by a mate or something.
I dont think the MAF would stop it running completely cause when mine went it ran rough and idle was up and down, she did stall but always restarted and drove, just chugged.
Never had an idle control unit or pressure sensor problem so can't really comment but if it wont idle i'd guess idle control unit, but that's just a guess
