Weird Cold Start - Pls Help

[koduRB25det]

Guys,

I have a problem in my R33 GTS-T S2. When I start the car in the morning [cold start] it starts weird. no problem in cranking the engine. It looks like bad firing/miss firing or running out fuel . But as soon as I just press the accelerator paddle it becomes normal cold start.

My spark plugs/ fuel filter just been replace. Check the tps voltage / coolant temp switch and voltage they ok.

So far I have clean my AAC valve/ MAF + check most of the elec stuff under the hood. Has no error codes as well.

Any ideas…?

Thank You.
