Default cold start woes!

Hey guys,

My 94 miata has been having this problem for a while now. Upon a cold start, the car will start up and idle very rough until it starts to warm up were it gradually starts to idle fine. Once its completely warm, the car idles like it should.

In the first minute of the startup, the car has misses randomly and smells a bit like a 2 stroke. I've changed the coil pack, plug wires, temperature sensor and injectors and the engine is still acting up.

Once the car has warmed up the engine will run fine. I can start it 45 minutes later and the car will run fine however if i wait for the car to completely cool, it'll start missing upon startup.

I honestly out of ideas now, waht do you guys recon it could be? What should i check...

Thanks for the help...
