Rotten Egg smell 95 T100
Recently bought a 95 T100.
When pulling up the driveway (400' drive uphill off the main road) and parking, there is a strong "rotten egg" smell. I don't notice any smell during normal driving.
Gasket of the O2 sensor behind the cat looked like it was leaking so I replaced it, but smell persists.
Muffler has holes rusted through from the inside along the bottom (probably water condensation).
Truck has about 85K miles. 100% stock engine and exhaust.
Any ideas?

It is you cateletic converter, all Toyotas do it. Do a search for suflur, cat, etc. There have been a lot of threads about this.

Switch to a different brand of gas. Some gas companies put more sulfur in their fuel than others.
Ive always had good results with BP/Amoco. No knocking, no sulfur smell and good fuel economy.

This is kind of an old post, but if anyone searches it...
That very particular smell and a signifigant loss of power (more noticeable at highway speed) is exactly what happens when your catalytic converter dies. Typically a chunk of the element inside will break apart or loose, then plug/clop the exhaust. This creates a ton of backpressure against the engine and causes power loss. You might hear some jingling/rattling from under your vehicle, too.
