Hey SN, I have a 2005 GT with about 89k on it and I have the following problem: My car needs to pass emissions by the end of the year, and there is no check engine light (anymore), but the following monitors are still incomplete for about a year now: Catalyst monitor Misfire monitor Comp component Oxygen sensor mon Oxygen sensor mtr I bought the car with a tune on it from a dealership. I did not know that it had the tune still on it. I do not have the stock tune because of that, and I do not have the factory cai/airbox. Mods on the car are bbk cai, slp exhaust with resonators deleted, and an unknown tune. This is my daily driver so without this car passing emissions I am screwed. All of your help is greatly appreciated. Thank you!
