someone correct me if i am wrong, but isn't the rotten egg smell usually caused by a bad or on its way out catalytic converter?

 

yessir theyre usually the cats are dead

 

I would not automatically assume that. A problem with the mixture (too rich) could cause it. How's your fuel economy?

First thing I'd check is that the vehicle is in proper tune.

 

what do you mean proper tune?

Hmm the gas milage I would say it is average I get near 600km on a full tank that is from full to empty empty.


And supposing it was the catalytic converter how much is a oem replacement.

 

The sulfur smell is caused by the cats working overtime from alot of fuel being introduced. On a hard accel it isn't uncommon for this to happen, but if you are smelling it under normal circumstances then it is time to have the car checked. If this goes on for too long you will end up destroying the cats.

 

I've had that smell 3 times in my car since I bought it. My garage has a steep incline and if I over do it while backing out of it I get the smell, too much gas while shifting.

 

jump on the car every so often and blow out all that crap and see if it clears up.you wil see a lot of black behind you.
that is if you have no engine light on.

 

It is raw fuel on a cold cat conv. The exhaust odor was common in the USA when the sulfur content of fuels was much higher. Air pollution rules changed that. I have not smelled it in years. Apparently Canada has not lowered the sulfur in the gasoline formulas.

 

You may want to do a couple rounds of seafoam treatment. I don't know if it makes a difference on a cat but it's worth a shot.

 

Thanks for the input will have the shop check it out next week when i go for a oil change - I have no cels coming up

I was going to change the exhaust in the summer with a 2.5 tt. What are your opinions on getting the tt high flow cat with the downpipe and cat back? Is it worth it?

 

If you have the funds then I would say do at least the downpipe while you've got the cat off. That means that they can just cut the pipe by the flex pipe and pull it straight out. See if you can get a break on the price by not making them have to undo the downpipe/cat flange which can be a royal PITA. If you get it done to at least the flex pipe then you could always get the rest done later. Or even do it yourself. As for the tt high flow cat, it depends. If you have any aspirations of putting on a K04 or bigger then I say go for it. It's cheaper than an OEM cat and you're set up for later. If you just plan on sticking to a chipped K03 then a regular cat should suffice (assuming it's $50+ cheaper than the tt cat).

 

Yhea I am going to do the whole thing one job. And yes next summer the engine is going to get the k04 upgrade and all the supporting modifications.

I like to do things in a logical order even if it requires spending some money.

 

That's what I did too. Once I decided to go the K04 route it was nice not to have to backtrack. And now that I've blown my K04 it's nice to be set up for a GTRS:driving:

 

On the topic of rotten egg smell, do you find that it boosts your libido?

yhea I get real horny when the smell enters the cabin...


on a side note I think the issue is due to different gas comapny sulfur content. It is really a random occurence and seems to be present in batch format.
