And I have no idea what the shop did. But I paid for a finished product. So making it right is the shops responsibility. If a product flaw makes it impossible for a shop to make cars run right or reliable, I'd still say this is the shops responsibility for selling it.

Once it's right, besides changing oil and keeping gas in it, what do I need to constantly diagnose?

My little brother doesn't know anything about cars, engines, tuning, parts - nothing. But he wanted his celica gts to be faster. So 7 years ago he paid a local shop to fab and install a turbo kit on it. He paid another local shop to tune it. He's changed the air filter a couple times, changes the oil, keeps gas in the tank, and drives his car. To this day he still knows NOTHING about how anything works. He turns the key, magic happens, and he drives.

It's a little more complicated than that for the FA20 engine. The 2ZZ is a good engine...much better than the FA20...
