Catalyic Converter???

Question

I have a 2001 Chevrolet Metro LSI, it has 97K miles, sometimes when I crank it up, it smokes just a little bit for a second or two...then sometimes, when I am driving it, it starts to smell like the rotten eggs smell, so I know it has to deal with the catalytic converter, but is it something that I need to worry about????

Answer 1

Smoke is fine for a few seconds, but while driving its bad. no matter what color, bule, black, or white.

now the smell of rotten eggs maybe coming from your battery. Batteries tend to have a reall y bad smell when they're going bad, have that checked out.

why do u suspect your catalyc converter?

Answer 2

i would say change that cat,if not in the long run your valves will get carboned up and its really gonna start to run crappy

Answer 3

It is very important that you deal with this issue. many things can happen when a converter fails. first when is clogs it will create a surplus of exhaust back pressure which could damage your engine. second if it clogs too much the internal temperature will climb and it could result in a fire.

Answer 4

White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket. Black smoke is caused by a rich fuel condition. Blue smoke is caused by oil consumption. The smell of coolant inside your car is caused by a leaking heater core.
