Car has MSD 330 chip, with closed loop.
Car is starting also badly, when itīs cold. When engine is warm idle is ok and also car starts fine.

Changed parts:
-MAP
-Fuel pressure regulator
-Air temp sensor
-Coolant temp sensor
-Inlet gasket (was leaking from middle part of inlet manifold)
-Fuel pump loom
-Spark plugs

Done so far:
-Checked fuel pressure
-Cleaned ICV
-Adjusted idle (plug OFF ICV socket, turned electric devices off and adjusted idle speed to 500-600RPM and then plugged ICV socket back)


Next ideas:
-Lambda?
-Clean injectors?
-Faulty injector?

Ideas welcome....
