surging idle.i found the problem,the o2 is readin lean so the ecm just keeps adding fuel.the o2 sensor will not change from .45 volts.so the motor is running really rich atm.thing that pisses me off is the o2 sensor is only 3 weeks old,luckily i have another one that im gonna go drop in in a few mins
