I am having the same problem also when two of my other friends RSX's smell just fine. We all use 91 octane gas from chevron and mine is the only one that smells bad. I don't know why either? My dealer told me it was the catalytic converter, but I just don't know.
As some of you may know the rotten eggs smell is probably coming from the formation of H2S (hydrogen sulfide). This smell is usually formed in the catalytic converter and is detectable at very low concentrations. I think this is caused by having a hot catalytic converter, sulfur in the fuel and a rich fuel-air ratio. The sulfur in gasoline is highly regulated in North America, but regulations may vary by location. All gasoline contains some sulfur.
From reading other treads, this problem is common with some Honda/Toyota engines, but goes away over time (after a few weeks). If you are unsure ask your mechanic, but I would wait and see if the problem goes away before doing a major repair. Especially on a new car.
I am thinking of buying an RSX, appreciate your comments before I buy.
Don't buy an rsx esp type s biggest mistake of my life too many problems and hard to upgrade parts.
Don't listen to the people complaining about the car, they are just nit pickers. The car is awesome, I just sold my 02 RSX cause my family got bigger, I am now in the market for an RDX. Very low maintenance, unlike BMW 3 Series, which are designed so delicate one missed oil change and it's goodbye head gasket.
I have a 2002 RSX-L with less than 59,000 miles.
The engine light came on again this week, and the dealer is telling me I have to replace the catalytic converter. The original converter was replaced at 38,000 miles under warranty, but this one is on my dime!
I take very good care of my cars, faithfully taking them in for all scheduled maintenance. I cannot understand why a car would need 3 catalytic converters in 8 years? Just does not sound right, and I'm not getting good answers from the dealer. This is an expensive repair at $1,200-$1,400. Something is wrong.
