need some help my 1992 4 door LS legend smells like rotin eggs. not all the time i change the mufler and the cat.all aftermarket but still smell any help THANKS :vomit:

 

[latinrasco]

its the aftermarket cat that is making it smell like that

NO WAY. ITS NEW

 

[latinrasco]

no im not joking...

i've smelled cars with aftermarket cats and some of them have this smell.

but it can also be caused by bad egr valve or bad oxygen sensors....

did you have the smell before you replaced the cats?

the rotten egg smell is sulfur.

yes i did have the smell.all change the mufler and the cat do to loss of power and the egg smell.but its still the same :bowdown:

bad egr valve.how do i find out if its bad.do i change it.and oxygen sensors.ohh and last what is sulfur

 

[latinrasco]

sufur is an element.... and unless you have the check engine light on then it shouldnt be the egr valve or the o2 sensors.

no my check engine does not light up.but wont a bad 02 sensor the check engine come on.i do use 93 oct gas

 

[latinrasco]

that egg smell is due to sulfur... which has to do with the exhaust system...

but my think is i put in a new mufler and a cat.thinking that it would fix it

I will second bl420, its usually the exhaust system when you smell sulfur.. Most of the time its a leak in the catalytic converter that produces the smell. He said its not that.. So its prolly o2 sensors, it could be a leak of some type (oil, radiator, brake fluid) , but they smell a lot different..

my catalytic converter is new.my legend is in the shop know any info to let the thec know what to check. thanks
