strange noise from exhaust?? over the weekend i noticed a odd "chirping" like noise coming from around the driver side collector (gets louder and faster when backpressure and no throttle is present ie above 3k on a downshift) mabey an hour after i threw a code po134 - 02 sensor ckt no activity bank 1 sensor 1- on the way home from getting the code read i must have knocked the senor loose drove it home mabey a mile or two waited for it to cool off repluged the 02 sensor and tighten the wires up, but the noise is still present i havnt cleared the code yet but i was wondering if i could have damaged the 02 driving the car without that one pluged in ???Will an o2 make noise like that if it has gone bad???? any suggestions or ideas
