your throttle body airflow could be the issue, return it back to stock ( you may add 10% on 0.90 and lower if needed )

you may rework your VE table from the beginning.

thanks for your helping , do i need to re active my ve and ? reset LTFT then start scanning ?

Do a throttle reset that normally helps fixing problems with this. Add airflow and always do a reset on your fuel trims when your tuning your VE

Is there any method to tune the TB airflow?.

Yeah, it's similar to tuning GM vehicles. You have 3 tables to choose from, Throttle Body Airflow, Desired Throttle Large Range and Small Range.
