air/fuel sensor removal -- help

[Caddisfly]

Hello.

I just tried to replace the air/fuel sensor on my '04 Tacoma, but I could not remove the nuts that hold the sensor on to the manifold pipe. My theory is that twelve years of extreme heat have "welded" the nuts to the studs. Does anyone have a suggestion on how to loosen the nuts?

Thanks,
Dave
