it almost smells like rotten eggs if a cat went bad. however i dont have a cat. and its only when my car is off is when the smell builds up. im baffled and lost. any guess's out there?

 

take the bodies out of the trunk and back seat

 

Stop farting!! j/k maybe something crawled up some where, maybe a rat??

 

use the dumpster in the ally nex time

 

lol u guys are hilarious. i think tomorrow morning i'll check my exhaust and what not for plastic bags and look for that possible dead mouse. but i neeeever run over bags or anything and if i do i always look out the back to make sure it didnt stick. maybe i missed one?

 

i had a really bad smell like that and when i looked into my trunk there was over an inch of water in there and everything was soaked . The root of the problem ended up being that my water drains from my sunroof were clogged at the bottom and when it rained or i washed my car the water wouldn't drain properly and get backed up then run under my backseat and into the bottom of my trunk. The mildew ended up being what the smell was pretty frustrating but an easy fix.
All i had to do is take the air hose to the bottom of the sunroof draintubes in my trunk.

 

you know it def did rain up here for a good 2 days... that mightttt be the issue. im def checkin it out. thanks bro def

 

no problem man. i dont want anybody to have to experience that death smell and not know what it was like i had to haha it was horrible.

 

any luck?

 

Ever tear out the interior of a car that someone blew their own brains out in after it sat for a couple months...? I have...thats the true smell of death...

 

The rotten eggs you describe makes me think you may be burning a bit of coolant, but if it only does it when the car is off, that's strange. I get that smell from my car, but it's when I'm driving exceptionally hard. GM cars also have a tendency to burn coolant. It's worth looking into water leaks into the interior, especially since you said it's been raining and GM weather stripping doesn't always do very well versus mother nature.

 

I agree with water inside the car from rain

 

mouse climbed through exhaust my guess

 

i was really worried i was burning coolant or something in that neighborhood. the smell suddenly stopped smelling. idk friggin weird as **** if u ask me. i looked in my trunk n such. no water anywhere, not even damp spots... on the good side i changed my plugs n air box mod filter. and my coolant temp never see's 200. during cruise im at 178-183. at a red light or in bumper to bumper traffic ill be all over from 183-199. that being said i have 75k with stock coolant. but i was always told if its not broken dont fix it. so when my cruising temps become 188 and up i will check the coolant and replace it. when lisa cools down tho i will check the smell of the coolant def.

 

our thermostats shouldn't even open till 180.. How're you running at less than that?

 

Maybe an ex took a **** it in?

 

battery could be going bad. it could be many things though. last time my other car smelled like rotten eggs, it was the battery.

 

I've smelled this smell in my car before too and didn't know what it was until I saw that the hooker in my passenger seat's legs were open.

 

Yea. Dirty egg vagina hookers FTL!!!

 

too be honest bro i dont know. in the winter she will run at 176-178 on the highway. i have NEVER changed the thermo. im at 75k right now with stock rotors still. stock clutch also and i have been running my mods since 30k.

 

yo i had to jump my car this morning... that must be it, when i opened my trunk to grab the cables i smelt it strong.

 

Many that could have ended really bad with the battery in the trunk....

 

hey i have a question with the battery. wats up with that little vaccum line that runs to the top of the battery? what is its purpose? mine falls out

 

check you battery i hat the same problem and my battery was bad

 

it's worse when it comes through the vents
