    did you check to make sure the floor mat isn't jammed up under the go pedal? Might sound stupid, but it does happen.

    if you have access, test your fuel pressure just to eliminate the fuel pump and delivery system. if thats ok, it might be ignition

    take your intake lid off and check to see if anything is blocking the mass air flow sensor or screen or any part of the induction for that matter. I once had the tape that seals the K&N filter come off and was sucked to my mass airflow sensor and blocked the incoming air which cut power significantly
