can anyone solve my prob?

from time to time I get a rotten egg smell from my exhaust it will last for

approx 1 hr and it goes. It might be three day's before it returns. I have

asked a hyundai dealer if it is common problem and they can't or won't help

otherwise it's a great car. Any suggestions please

Although manufacturers are typically not willing to divulge this, the
amount of nickel in the converter can affect this. Hyundai will not
release this type of part update info to anyone in this country, so I have
no way of determining whether a new converter will solve the problem.

To start, have someone very familiar with the product check it to see if
all the fuel management data appear correct.

If ok, try switching gas stations. Sulfur content in the fuel can affect
the odor.

Your catalytic converter is currently working properly, since you have no
check engine lamp. 1998 models are required to monitor catalyst
efficiency. If nothing is found amiss, I'd recommend living with the
odor. I think that's better than attempting an expensive repair which may
accomplish little or even make the condition worse.
