hickups

When I start the car on cold it starts shaking for 2 - 3 mins having those kind of like hickups but then it starts working fine, what can that be ?

If you are running a Procede, update your harness as posted here. Some DME versions don't like downpipe fixes. Even when they are turned "off" or set to minimum strength.

HPFP Injectors plugs coils. If no codes thrown, fuel pump and plugs can yeild a rough idle.

When it starts shaking as you've described, what is your RPM; like less than 500 RPM's? Right before my HPFP failed, the car would start from cold and shake. I had to kick up the idle until it would stabilize at 1100 RPM.

In my case, I needed the HPFP replaced, all spark plugs, and my injectors.

this car is fucking anoying, I will bring it to the dealer he'll say O no codes sorry, it hickups for like a minute after the cold start and then becomes normal

That IS normal. My car rough idles when it's colder outside then smooths right back out when it warms up. At worst you might have some carbon build-up.

Thats sick, can you post the dyno if you decide to go? I feel a lot more power in this cold weather...I am going to put mine on the dyno as soon as I can figure out wtf is up with my procede and install my fmic and dp's. Ordered um, got um here, now just gotta put um on.
