How are you powering the sensor? The sensor heater needs to be powered ONLY when the car is running. You can shock O2 sensors with cold water vapor if they are hot while car is off and you start it up (e.g. you have it tied to accessory power, turn car off, listen to radio etc, then restart - O2 will be hot and die when cold water vapor in manifold hits it). You can also damage O2 sensors by having them off while engine is running for extended periods.

Hmmm - now I'm thinking why didn't I do that (instead of going to the relay output). Is the fuse before or after the relay? I actually used a fuse tap on the relay output. It was a pain pulling out that relay too...EDIT: Or did you mean you tapped the outgoing wire? That would've been easier too. Oh well, either way works.
