ok so i have an 06 ss/sc and latley it starts sputtering while im driving, and the when i stop it wants to just die all together and there is this horrible smell. i have noticed that this happens when it rains really bad, but im not a mechanic. The only mod i have is an injen cold air intake, I had thought that it might be taking water into the engine,but im unsure. Any one else had the happen?

 

does it smell like rotten egg it could possibly be a really badly clogged cat can you step on the car without it sputtering and if you can what is the boost level
i think you should take it to a shop

 

Yeah sounds like a cat, I'm probably less of a mechanic then OP, but this happened to my friends highlander and we thought it was the cats but it ended up being his timing belt/chain thing being off by a few teeth, but we do have poop cats

 

Hmm, if it only happens when it rains, it may be the MAF sensor getting wet. But that dosent explaint the smell.

 

mine did that before the cat went bye bye lol, the cats have a 80 ks warranty on them, and some special recalls upto 120 ks if u fall into any of these catorgories take it the dealer...

my car's symptoms when my cat was clogged :

* Bad Smell
* Sputtering
* Boost Over 20 psi on Stage 2 lol
* Power Reduced Big Times :x

 

maybe he goes boom boom in his pants when he finds out his car shuts off? jk, jk
sounds like it might be that your running extremely rich and killed the cat?

 

I don't know

 

im kinda new to the forums when you sat cat you mean catalitic converter?

and yes there is a smell of rotten eggs, like i running rich. how would i fix that

 

yes cat mean catalytic converter and if the cat is the problem you just need to have a new one put in go to the dealer the cat should still be under warranty

 

well it doesnt do it all the time it happend the other night and has been fine since, and as long as i have my foot on the gas it seems to run ok, but with a little sputter

 

i dont think it is the cat then and you said you had no cel
have you cleaned you maf and throttle body yet

 

no but will try
