Ok, since you bought it all you changed was the air filter. If you have not changed the rest (including the trans. filter/fluid) then I would do all that. Whenever I buy or get a used car I always assume that none of this has been done and change it all. Doing this ensures that I know exactly when everything was done and there is no guessing. I never assume the previous owner changed anything on schedule. I'd be willing to bet that those are the original plugs and wires and your plug gap is way off.
