Service Engine Soon...did I destroy it?

EYE ESS

Good afternoon ladies and gents,

I am requesting the help of the 370z Guru's. I received a service engine soon light 300 miles ago. I called Nissan and they said it was most likely the gas cap not tightened. They said problem should go away in a hundred miles. Due to this I ignored the situation. I just had the genius idea of looking under the hood and one of the intake tubes from my stillen Gen 3 came loose from the hose right next to the motor. Therefore my engine has been sucking in air without the filter for the past 300 miles.

How much have I damaged my engine?

What should I do to fix this problem? I already tightened all of the tubes.


Should I reset the ECU to see if the error goes away?

Thanks so much,
Justin

If you need any additional details please let me know.

*The car did vibrate rough in idle a few times. It felt like my RSX when I had motor mounts installed.
