I'm not sure about the stepper but air comes out in all of the right places based on what direction I choose. The previous owner replaced the timing belt, water pump, etc. within about the last 5k miles. It uses some oil, about a quart in 1000 miles.
It runs and drives fine. Paint is awful with the clearcoat peeling and door handles, mirrors and spoiler fading.
Think of it as a parts car you could drive and enjoy.
