Ok ,so i searched for an hour on all the different write-up's on pulling ECU codes, and what issues the numbers reference.

After pulling the codes, I come up with....

25 - IACV-AAC Valve81 - Vacuum Cut bypass Valve87 - EVAP Canister Purge Control91 - Front o2 Sensor92 - ?93 - ?105 - EGR and canister control valve (Solenoid)132 - ?

Like I said I searched on these codes and I find nothing on 92, 93, or 132, and I've double checked I am looking at them correctly. I probably cycled through the codes 4-5 times just to ensure I wasnt mis-reading them.

Other than the CEL this car drives perfect. It doesnt idle funky, get terrible gas mileage, etc. I have noticed that the car has an exhaust leak, most likely why its throwing the o2 sensor code, however I have no idea why it would be throwing the IAC, EGR, Etc codes.......i have checked around and it does not seem it has a vaccum leak...

Any help is appreciated, thanks
