K series problem MG TF

Hi all,

Sorry for asking this here but I'm hoping someone might be able to help, it is K series related but in my 2004 MG TF 135. I have posted this over on the other forum.

Does anyone know why my car smells rich and stalls on cold mornings ?

It starts fine and ticks over fine for about 30 seconds (never timed it) and then starts to play up, the tickover speed starts to lower, it's starts smelling rich from the exhaust, the tickover starts to get lumpy.

Its drives fine, no missfire etc. But dip the clutch at a juction and it stalls, and sometimes it's difficult to get it to restart.

Once the engine is up to temperature it's fine.

I have a T4 and it shows nothing weird. (that I can see)
I have changed the LAMBDA for a genuine BOSCH one and that made no difference.
I have changed the ECU coolant temp sender, no difference.
I have checked and reset the IACV idle valve and no difference.

Any ideas ?????

Thanks

Pete.
