Sulfur Smell-89 Le Sabre

[mambo77]

'89 Le Sabre with 167,000. It was missing, but new (G.M.) plugs and wires fixed that .

I was getting a terrible rotten egg / sulphur smell at idle of more than say 1 minute.

Had a new catalytic converter put in, but the smell still occurs after several minutes...but not consistently.

Any ideas???

Thanks for your replys!

heater core smeels bad when they go. Does it smell when you have the air on or when its just idleing?

It isn't a constant smell, but at idle, after several minutes (and the engine has been run for under 20 minutes), the sulphur smell will come on occasionally.
