Dani, Un plug the O2 sensor from the rear fire wall and re adjust the fuel mixture screw in the air flow meter till you get a smooth idle. (Make sure the 3 screws on the throttle body are all screwed in and the idle speed motor valve is open or running as we say.) I would then turn the adjustment screw counter clock till the engine starts to shutter which will tell you your all the way down or real close, then turn it clock about 1/8th turn and it should smooth out. Then re attach the 02 sensor and give it a few minuets to adjust it's self. Let me know. Normally you should never have to move the screw adjustment more than one turn either direction. Once that is don't if you install a new 02 sensor it should keep everything just right pending no other trouble.
