General Bravo t-jet sport boost problem

[Sariah]

Hello guys !
I have 150 Sport t-jet Bravo
I have a problem with accelerating
When I press the accelerator and turbo boosts full the car start trembling like there are no enough fuel pressure or there are overboost from turbo !
And sometimes when the tremble happens check engine light flashes for 10 seconds then stops when calm down !
Most times it happens with full turbo boost ( 3000 rpm ) when rpm goes more like 4000 or more the tremble disappears ( when turbo not boosting full )
Tremble is like the car want to accelerate but something stopping it and the turbo sound like stuuststststuuuuu lol
Need your help please!
Many thanks.

errors?

From the symptoms it could also be a bad spark plug or ignition coil, map/boost sensors etc ... a lot that can go wrong.
Read the errors... work back from there.

Yeah spark plugs are what I'm thinking about right now.
Overboost has been fixed by cleaning boost control valve ( the solenoid) but the engine vibration is still happening when Throttle is full opening
No fault codes because of faulty ecu ( I had a problem with ecu can't record error messages after shutting down )
