Sulpher Smell
1995 ZR-1 with 20,000+ miles on it . I noticed a few times now that when starting the car, it sometimes gives off a sulpher odour but not with every start .
I think it did it once with a cold start and twice with a warm start or visa versa. Is this a sign of the catalytic converters going or something else ? Or bad fuel ? ... Mike |

Re: Sulpher Smell
Well it gets driven once a week and I usually use 1/2 to 5/8 at each fuel up ... When I started it today , no smell , but yesturday it did smell on startup for a short while then cleared up . Put $40 in today and went for a 2 hr drive (always hightest) .
Seems fine today . Sent from my LG-H831 using ZR-1 Net Registry mobile app |

Re: Sulpher Smell
A sulphur smell immediately brings my mind to an overcharged battery condition.

Re: Sulpher Smell
Hard WOT with Cats will give you an Ozone smell, not sulphur.. don't believe it's you're catalytic converters.. might try going on a long drive at highway speed to clean out the older gas and put in fresh.. not really sure that would be it though. Haven't heard of sulphur smell from bad or failing battery.. certainly watching to learn though.

Re: Sulpher Smell
I am thinkin also that it was just a bit of bad fuel . Had it out today for a highway run and fresh fuel and no smell with startups .
Thanks for the replies Mike |

Re: Sulpher Smell
The smell of SULPHUR? Hmmmm..... According to the Bible, it might be the company you keep, Mike! (JK
 )It smells like sulphur to me too; like you said: "...not all the time": just once in a while. But, I wouldn't swear that it actually WAS sulphur (or sulfur [Americanized spelling]). And, not necessarily exclusive to the Vettes either, BTW.
