Its probably running rich because of the 02 sensors or something. I would data log them and see whats happening.

lol, i was hoping to grab more attention describing it like that

...a potential move to OT did cross my mind because i did describe it that way, but what it comes down to is the fact that:

i thought i'd bump this to try to get my seafoam question answered.

does anyone have a pic of which vacuum hose to send it through? i've done a bunch of searches (on here and on other sites) and haven't come up with a definitive answer... (i can supply a pic of my engine bay if need be too). i'm pretty sure i know which hose is the right one, but all the 'example' pics i've seen are for either an sn95 or a new edge, so i just thought i'd ask to make absolutely sure i use the right hose.

please help......

Xeno,

Can't help you with the Sea Foam question, been researching that topic today as well. If you do a search for Sea Foam you will find alot of threads about it.

Have you made any progress with the exhaust smell?

I'm hoping that he has found a solution in the past three years. Maybe he can chime in and help you out.

wow, talk about resurrecting an old thread!

i did actually figure out the seafoam thing (thanks for the vid though 07). as far as the smell, i just attributed it to the sulfur in the gas... i've moved to a different state since i originally posted this and while it isn't as bad, i still notice it on occasion... oh well

Thanks and have a good one.

^^ glad to hear the smell for yours has gotten better, but i would still do the seafoam as sort of a preventative measure and just to clean all the junk out... plus it makes for a good smoke show

The fart smell is H2S.

You can test your sensors with a DVOM. It's easier off the car but can be done with them on the car.

a 7 year old car with such low miles hasn't gotten driven much which is why I'm leaning towards fouled O2 sensors. Burning rich and the cats can't convert all of the H2S from the engine to odorless

The sensors could be responding within spec but with limited range. Corrosion or fouling will cause this but not necessarily throw a code like with a defective circuit within the O2 sensor or a sensor that has just plain failed.

H2S is corrosive by itself (Acidic Gas) so you may also start to see some blackening at your exhaust tips.

LOL just realized OLLLLLLLDDD THREAD! Sorry!

Check the sensors, if those are fine, I'd look into the cats next.
