When Im driving and my car is running on idle rpm and I press throttle it starts to stall and rpm wont go over 1500. After few times it stalls and loses power it gets better. So the problem is going from idle to acceleration, so Im guessing theres something wrong either fuel mixture or fuel supply. Where should I start troubleshooting?

I used to have problems with starting the car put it resolved when i took the electrical connector out of the cold start valve. So I guessing that theres also something wrong with the thing that sends the signal to cold start valve to supply more fuel.

I had similar issues and thought it was fuel related, randomly I replaced the ignition coil and distributor rotor (Bosch only!) and the problems went away. Start there first...
