It stinking pretty bad after a few hills. I have 53k on the clock, and no cels. Maybe an o2 is starting to shiz the bed?

I've heard that a sulfur smell (similar to rotten eggs) usually means your catalytic converter is failing. I don't know for sure though, might want to do a search.

Could be that the gas you're using has a high sulfur content in it.

I've noticed that rotten egg smell with new cars, so I thought that the catalityc converter was supposed to do that as long as it's good and working.

Maybe if it smells worse, it's more environment friendly, who knows...

It's actually the result of the cat working overtime. The catalytic reaction breaks the unburned fuel in the exhaust into its components and recombines them into other compounds- H20, CO2, H2S. An excessively rich mixture and/or high sulfur content in the fuel will produce a higher amount of H2S (hydrogen sulfide) from the cat which is what gives the rotten egg smell. As mentioned a different brand of fuel may help, and the engine control system should be checked as well. It is very possible for a failing 02 sensor to cause this but not set a CEL.

Default Back from the dead....

I went on a 90 mile drive which has its fair share of hills. Speeds are 55-70 all the way through.

Anyway, every big hill or long gradual slope I would either get on the gas a little early for momentum or drop down to 4th for extra power. A few times doing this I would get a distinct sulphur smell, and when the road leveled out the smell would go away.

I had a ton of camping supplies in the car with one passenger.

I've got 90k on the ticker.

Is the cat dying? Or are my borla's (unwrapped) causing problems for the converter?

I too, every once in a while smell the sulfur smell from my car. I have a 97 2.2L with 88k on the Odo. Only smelled it a few times though, so I'm not sure what it is. *shrug*

Could be related to the battery. I had an older Ford pickup that smelled like rotten eggs . The cause turned out to be a bad voltage regulator which caused the battery to give off sulpher gas due to overcharging.
