Just wondered how the air/fuel ratio could be adjusted on an 04' GT? I've read alot about trying to maintain the optimal 14:1 ratio or so, but i am curious how I can tell where my car is in regards to that ratio and how it can be tweaked?
If you want to know what it is, just buy a wideband o2 sensor and gauge and check it out.. although I see nothing in your sig which should have any affect on your A/F ratio, so it's probably fine.
you want 14.7:1 a/f ratio during idle and part throttle. the cars computer automatically adjusts itself during these situations using the stock 02 sensors. as long as the sensors are operating properly, you'll be running 14.7:1 when you want to be.
