when my car miss fires its when I have it turned up to 10 lbs of boost.. I have replaced all spark plugs and coil packs.. the funny thing is. it will take to boost at half throttle, when i punch it at the same amount of boost the car starts like jumping.. I know its running lean.. do you think that affects the when i punch it.. is it not getting enough fuel.. or is is my 02 sensors. or could it been my catalatic convertor being plugged..
