I did some boost leak tests and found a few mainly the throttle body. I replaced knock sensor but i am still having symptoms. No knock any more but the car has very little power. It seems like either i am having a spark issue or air flow issue.

i notice airflow and mafraw seem to flatten out while trying to accelerate. i am not very expeireince in reading my stft and ltft yet. But it seems like CombFT is in the negative alot?

thank you,
