and i think my car is running rich, any ideas what is causing this??
let me know ! thanks for all the help guys !!

...that's normal bro. the a/f gauge reads a specific volt or resistance reading. when exhaust gas passes by the O2 sensor, the sensor converts this into an electrical input to the ECU. this electrical input fluctuates because gas flow is not steady. there is nothing wrong with that. once u press the pedal hard, that is when the reading becomes vital.......
