Replace the coil. It is shorted out. I have changed quite a few coils for the exact same symptom.
The graciousness of a FixYa rating for my assistance would be appreciated.
Thanks for choosing FixYa for assistance.

I suggest you have the injectors tested by the dealer, the sludge buildup will not cause a miss fire. to clean the throttle body use carberator spray while holding the engine idle high.

Clean mass air flow sensor with a nonchlronated brake cleaner,install new air filter and check all vacuum lines for leaks then check for vacuum leak around or at intake manifold.Code P0140 is for mass air flow sensor code P0300 is a multiple misfire which more than likely is a vacuum leak possibly intake manifold gaskets leaking.
