Hi there
I would suspect then Lambda or Coolant Temp Sensor,those two things can cause those things
Do you have Torque app if yes then monitor Coolant temperature and Lambda hardly you can monitor via OBD as they don't read as wideband
Thanks,Jura

That's strange about the Torque,but you can try SSM monitor and you will see,please if you could monitor Coolant and Lambda
Thanks,Jura

yeh that looks pretty rich, mine went a similar way before the heater circuit died in it and it threw a code. Was bananas at cold start for a few weeks beforehand though.

Lambda
My 03 uk Sti has a strange stutter/hesitation missfire when cold for the first half mile then clears also uses a LOT of fuel when cold or crusing it uses less when it gets the boot when it gets the boot! I was thinking of replacing the front lambda does this sound like what yours did? Also how hard was it to remove I've heard they can be a pig?
