I put new o rings in. And the injectors were cleaned right, how would I go about testing the sensors? And what sensors should I be testing?

Try cleaning the IAC with carb cleaner, it worked for me on my honda.

It never hurts to run a fuel system cleaner. just keep up on the oil changes and you should be fine. at 30000 miles I would do spark plugs, oil, trans fluid, and if you really wanted to take good care of it, you could even flush your radiator and run new coolant.
