    My F430 misses badly when given a lot of gas suddenly. The car shakes. This just started at~29k miles.
    Any ideas?

    The fuel pumps have low and high speed relays, new relays are cheap so might be worth a look

    Sounds like a misfire or throttle body issue (either TPS or the flap actuator).

    Needs diagnostic and data logging to confirm.

    Proper diagnosis is imperative to determine root cause this will eliminate all the guessing.
    Scan the codes and then monitor parameters...misfires have multiple factors.
