SOURCE: rotten egg smell

Change the Oxygen sensor or circuit. This can cause the catylytic converter to permit the sulphur smelling fumes to go through. i believe that there is a product out there in the market for this very purpose. i don't remember the name. but you can ask. It is are sold at auto parts stores

When you say smell like exhaust, does it smell like rotten eggs (sulfur)? If so, could be catalytic converter clogged up.

My car has a rich gas smell then when it warms up smells like rotten eggs does it have something to do with the cadillac converter?


Maybe.
The rich gas smell is probably due to injector problems. The rotten egg smell is sulphur in the fuel, which reacts to the catalytic converter. The rich smell would need to be fixed first by checking the injectors and the engine computer.

Whats the problem smells like rotten eggs,no power, car chugs and bogs down ?


Sounds to me like the catalytic converter is shot. The "rotten egg" smell and stalling out is a dead giveaway. The converter is plugged up and cannot let the exhaust out of the tail pipe like it should. The exhaust is building up back pressure in the exhaust system, causing the engine to lose power and stall. Take it to a qualified shop and have the catalytic converter replaced.

check O2 Sensors, add a product called Ametech restore at next oil change, this does wonders for your vehicle, improved my BHP & MPG threefold , also as you say it smells bad (Like rotten eggs?) this will be the catalytic converter, either replace or add a product called cataclean to the fuel & take it for a run, It literally cleans all the **** fro the catalytic converter removing that rotten egg smell

Car runs ok, but gets hot and rotten egg smell comes out of the exhaust


If car runs okay with egg smell, its normal and working the way it should, if car is running poorly and the rotten egg smell has gotten worse, its a sign that your exhaust catalytic converter will need to be replaced. good luck!

Usually the rotten egg smell is a clogged CAT. Is the engine light on and if so did you retrieve any codes?
