Trying to get my head round MAF and Carb, I think its just a throttle not a carb?
I'd pull the plugs, give it a turnover first, if fuel is getting there and not starting the plugs will be wet.
Always worth cleaning out the throttle body, sticking butterfly valve can cause all sorts of silly problems.
I've got a simple code reader here if you want me to drop it off or give it a quick run.
