Just my 2p worth, I have a few K-series cars (2 x TFs and a ZR and I have a T4)
I also was having problems with rich running and stalling when cold. It turned out to be the IACV valve which was sticking, the grease in the bearing had gone hard. I took it apart (not easy to do) cleaned it all up, reset the IACV with T4 and it's fine now.
I'm not saying this is your problem though.
Pete.
