When I press acceleration quickly the car kind of shuts down, no power in acceleration it seems to be like the petrol doesnt reach the engine (suffocation). If I push acceleration slowly slowly it's working kind of OK. When I put 1 gear and start driving If I press acceleration slowly slowly it's kind of working, if I press quicker it's shutting down. But if you driving it from 1-2 gear and so on it's not shutting down. Seems to be something with air intake, maybe the problem is throttle body? Any Ideas guys? I tried to clean throttle body with spray, tried to change spark plugs, tried to change few sensors I've checked the ignition, everything is ok. Did not tried to change the throttle body, we tried to connect the computer to the car, but did not show anything

Based on your description, it sounds like the engine is starving for fuel. Have you checked the fuel pump pressure to see if it is within the manufacturer's specs?

Sorry did not mention, Yes the guys in garage they checked the fuel pump pressure, they said it's ok but if it would be the pump pressure problem it wouldn't go properly on all gears. But it's ok on 2, 3, 4, 5 gear it's not shutting down it drives ok. It's only when I start the engine and the car stays on neutral and then when I press accelerator quickly and hardly it's kind of shutting down but If I press it slowly it's ok
