Your only problem friend, is the temperature sending unit/sensor. Upon cold start, this sensor wil tell the computer to go into cold start mode putting a bit more fuel in and raising the idle a bit to keep it running when cold without using the throttle. Replace that sensor and your good to go. Makes sense, right?

feul filter.

You're not getting enough fuel. You should check your fuel pressure. If you have enough fuel pressure, your injectors are probably clogged up. Run a lot of fuel cleaner through your tank when you put gas in and see if it makes any difference. Lucas fuel treatment is the best to use.

I'm not familiar with this model, but have you checked that the fuel tank breather is clear?

bad coolant temp sensor,or idle air control valve, and possilbly just low fuel pres.
