I cleaned my T/B yesterday and use the cleaner touch the FiAV oring and the oring become bigger.

I put it back and now the engine light turn on and idle go up and down frequently.

Answer
Sunny,
Spraying any kind of cleaner directly into the T/B can cause problems.  As you experienced, the oring may now not be making a proper seal.  Also this can negatively affect surrounding electrical components, the EGR valve, and even the idle speed controller.  You may have luck finding an oring at your local hardware store.  You can even order one from your local Mitsubishi dealership.
Good luck!
