Dellz,

Any error codes? It sounds like a mixture control problem, and since it is on cold starts, the oxygen sensor is out of the loop. How is the fuel pressure? Fuel and air filters? TPS voltage? IAC air passages clean? Just some thoughts, but you should scan for codes anyway, since some of them might not set the MIL lamp.
