I get this really weird almost rotten eggish smell from my car sometimes. i think it comes out of the exhaust, im not sure tho. Anyone ever experienced this and can maybe help me fix it or at least explain whats wrong. I am running on 91 pump gas from 76 gas station.

 

probably the cat is gone, or you are running very rich.

cat. They reak when there clogged, gut that thing.

 

See now while most people will say that its a bad cat I ahve heard that all it is is the cat doing its job?? Not saying thats right its just what I have heard?? Best thing drop your cat take a look at it. If its bad either replace it or gut it or find a race cat instead of gutting it. How to tell if its bad it to just see if you can see through it or not is one dead give away if you cant see through it (look at like a strong light or sun to see) or if you can see through it look and see if the honey comb inside inside is like oily or covered with carbon deposits that could mean its bad also.

 

Smell the battery.


I am serious.

 

you get caught with a gutted cat and they will rape you in fines

 

My cat is a brand new. like 1 and a half weeks old magnaflow high flow carsound cat. so its not the cat. ill check the battery. i dont see any battery corrosion or anything tho. thanks for your help

 

i have the same thing in my 96 cavalier...like someone ripped one. i have a oil leak behind my engine block. why it smeels like that i dont know. that is the problem i do believe. you might have an oil leak...if none is visible..feel around the back of the engine block (when its not hot). hope this helps.

Amen to that.

 

i have no leaks anywhere, i must just be running rich? how do you adjust running rich?

 

Adjustable fuel pressure regulator....

 

I had a bad headgasket and it was overheating but the guage didnt say it was but that smelt like some nasty eggs.

 

It's your cat. Notorious for smelling like rotting eggs when they go bad.

yea if the battery is overcharged it will give off some hydrosomethin gas. carefull its flameable

 

im thinking of just taking it to this guy someone recommended for honda tuning and maintenance and asking him to check it out and see whats wrong with it. i dont smell anything coming out of battery and i know its not the cat acuse its seriously like 2 weeks old and i dont think it could be bad headgasket letting me overheat because bad head gasket would allow oil to leak someone right, well my whole entire motor, head and black is completely dry
