Why the smell??!!
Since I have been using the new EFIE with hydrogen on my truck, I've noticed the old "Rotten Egg Smell!" I've read where it could be a bad cat. converter of course, water in the exhaust, high temp in the cat., and even hydrogen sulfide gas. Just looking for you guys take on this. Oh yea, already thought of the local mechanics, but what do you think he'll say about all this hydrogen gear. "THATS YOUR PROBLEM!" Gas mileage is still 18.5 to 19.7 even in the the colder weather.Confused

The sulfur smell you describe is from a catalytic converter before it warms up. Is it possible you're not driving your vehicle enough to warm it up and it's the cold weather that's to blame?

Rick, drove about 25 minutes this afternoon. Noticed the smell again when I got home. Valves don't rattle, temp still at about 190 degrees, no check engine light, plenty of power. Go figure. Maybe just coincidence with HHO. Leaning towards bad cat converter. It sure isn't the smell of success.Tongue

Might have to break down and ask a mechanic. Sorry, I have no experience with cats, except I've smelled a few in my lifetime (but it's been a long time).

Turn off the hho and see if it goes away.

what kinda truck do you have??

I've ran across the same smell before... I have no explanation for it, other than 'it's the catalytic converter' it did go away the same day or the day after... from what i remember it wasnt on old tired busted a$$ cars either... it could be any car.. I don't think it's a problem, however colchiro has good advice.... try to unhook your HHO and see if it goes away... or drive for a day or 2 and see...

i hope this helps

Maybe bad too worse or even the solution. Decided to check production of cell today and, Nothing. After a complete once over, I found a resevoir full of whipped cream!Mad All this time of playing with HHO, never had a foaming problem . Anyway, drained the tank and mixed another batch of secret sapoo. Back to good production and after running today, no rotten eggs. Scared me a little. Glad to see the foam had not made it to the bubbler. I'll just cross my fingers and see what happens.

The only time I have smelled that sulfur smell is when I was behind a car and they romp on it. I guess a super rich condition from the acceleration. That being the case, I would think your vehicle would be running rich and the mpg should have dropped.

My 2cents worth. Glad you found the problem.
