As stated above you'll want to take it in for tuning. From what I've heard it's better to run rich than to run lean, less chance of messing up your motor.

You don't know how rich. Take it to a dyno and hook up a wideband.

You don't even really have to take it to a dyno to tune your air/fuel IF you have a wideband o2...
You can street tune your a/f curve for the time being, until you can get it to a shop to dyno tune it...

Yup. I have a wideband 02 and have tuned my car among with others myself using it. If you don't have the wideband though you are grabbing at straws and are going to end up hurting the car.
