2.0 V6 poor running after 30 seconds.

Hello guys.

I had a issue with misfires, replaced the pack on nr.2 and replaced all the spark plugs with the proper stuff. (they were about 100k miles beyond their lifespan

)

now it runs perfectly when cold...for 30 seconds.
after that time (its basically clockwork) the ECU seems to switch to a different program and it runs like a wet rag after that.

no errors on the dash, i plan on going to a T4 this week and hope if they see a error but the dash has not given any error so far.

i had a simmiar behaviour with a previous car but that was due to a lambda sensor that had a failed heater. but that one only did that when cold, once the exaust heated up it ran normally.

any idea what can cause this behaviour?

edit: read the codes, none were present.
