Evo2 stalls on cold start up?

Can anyone point me in the right direction?

She is stock as far as I know,I just did a full service and also had to replace the "ISC"(due to a no idle situation when hot).

What happens is when first started in the AM,especially if its cold outside,the engine barely fires up(feels as if only running on two cylinders),is rough,shaking and stalls.On the couple of really cold days so far the year I had to start it 3 times.On the second or third attempt it runs fine for the rest of the day until the next AM.

 

Check the coolant temp sensor.

Try unscrewing the BISS screw a turn,

Is the MAFS clean? I don't know if you have an oiled air filter, but that seems to be a frequent issue lately with the filter being too oiled and the turbo sucking some onto the elements inside the MAFS.

 

Unplug the mas. The car will run with it unplugged. If it starts then you know it's probably going to be a mas problem.
