As many of you will recall, I have a problem with rotten egg smell exhaust... Gas type, and octane seem to have no difference...
Well, I've come up with a theory, just wanted to see if I could be on the right track, of if I should just shut up cause I'm way off...
Anyways, my theory involves not enough exhaust flow running through the system.... so sulphur (or whatever it is that makes the smell) is being deposited in the cat?
My reasoning is my driving habit. I normally don't rev the car up very high (except when racing of course) An example, I'm usually going down Macloed trail doing 60kph in 5th gear, running about 1500 rpms. I'm not revving higher in 4th gear or even 3rd. I use overdrive quite a bit...
So maybe the constantly lower revving isn't putting enough flow through the system to drive all the crap out of the exhaust?
Yes? No? Maybe? Shut up and deal with it?
Thanks for any input guys!
