    check maf sensor of your car.
    Check all the coils
    Go for engine tuning.
    Clean or change fuel filter.
    Get your injectors checked as well.

    Have the MAF sensor cleaned, fuel filter changed if it hasnt been changed for too long and use liqui moly's fuel injection cleaner for a couple of tanks. The drive by wire throttle body doesnt have a separate idle control valve so cleaning it may not make much of a difference. If its dirty however, cleaning it would be a good idea to prevent the deterioration of the butterfly.

    by hydrogen fuel do you mean the AGHA WATER modification in the vehicle with HHO !
    lol these kids missed basic physics 101, you can't obtain more energy from hho than consumed to convert water into hho.

    I totally understand your frustration! as i too work on my car my self.and have to research problems i encounter.. after looking at your work list the only thing that comes to my mind is the resetting of your ecu( have you tried that) look it up on how to reset the ecu! or the simple hard reset remove battery terminals overnight . .another thing that i just realized! does your car have a catalytic converter? it might need cleaning!
