rotten eggs!
 

Well as most of you know my lil subie has like 120k miles on it, and recently I have noticed, especially when I am on Empty in my gas tank, some malodorous content. I know that that is typically the smell of a CatConv that is not functioning properly, but the thing is, it never does that when I have more than 1/8 of a tank. I am wondering if running on fumes or on E would contribute to the smell, or if its time to look at CVter Replacement.

And if I do go with a replacement, I dont really want to go back stock, but I dont want to go so far the other way either. Whats a good street in between system that I should be looking at? :?:

Wait a sec. You also have CEL, right.... Did you ever pull that code? Sounds like a something in your fuel system, vapor canister type stuff. That would explain both.

Yes the cel was that two cylinders were misfiring. That was the only history on the cel, and although I have not changed the plugs the cel comes and goes, at night time, its usually off, but in the day time, its on...its the strangest thing. And the CEL isnt always on when the smell happens..

Oh btw, I will drop that tire off tomorrow
