Hello,

My car has some serious issue since cold weather started :

difficult cold and hot starts : YouTube - E36 M50 difficult start (http://www.youtube.com/watch?v=SfQelsZWklk)

Runs like **** : YouTube - E36 M50 rough RPM / saccades dans les tours (http://www.youtube.com/watch?v=9Lyv7Axufhg)

On idle, clutch disengaged, when I kick down accelerator, the engine wants to die, nearly dies but then revs ok.

rough idle when engine is hot.

Running without the MAF does not change much.

I have those readings on all 6 coils (primary resistance) on the 4 ohms when cold (0 celcius)
after a while inside i get 2 ohms.

thx for any help.
