Misfire when Cold

Hi Folks,

My X1 is misfiring.
Cylinder 1, 2, and random.
No misfires on 3, 4 that I can tell.
She runs like crap when cold.
Sometimes goes into limp mode, which clears after a restart.
When warmed up nicely, she runs fine (but codes do not go away, not that they would).
I have purchased the correct Delphi Coils and NGK plugs, same as OEM.
I have not yet installed the coils/plugs.

Do folks have suggestions on what else to check that will affect just 2 cylinders.
Will a bad MAF affect just 2 cylinders?
Head gasket maybe?
TPS?
Throttle body?
Already changed the ECU as there was a fault.

Just bought this car (120,000km on it) so I don't know the history. And no, it had no code when I bought it...
