Tonight when I was coming back from class (the car has been parked outside for at least 3 hrs in MI temp) and I have noticed that everytime I step on the throttle, the car chock a little, and when I got home, I can smell the whole garage smell like rotten egg, I have searched the forum and notice that it could either be a O2 sensor gone bad cause the car to run rich or a clogged CAT. Now my qustion is that is the CAT covered under warrenty (read it somewhere that it is covered under some kind of Federal Law, my car now is 3 years old, have about 45,000 miles). Going to the dealer tomorrow just want to make sure they don't screw me over

any help is appreciated

Thanks

 

i would bet on a clogged up cat

 

Clogged Cat for sure and no warranty coverage as it is only covered if you failed an emissions test. One cause for this that I know of is using bad gas or low grade/octane fuel. Here in NM we can use 86 88 or 91 only so 91 is all I will use now.

 

Is this clogged CAT typical? I have only 1500 miles on my car and I just noticed last night the terrible rotten egg smell in my garage. What should I do? What exactly is a CAT? thanks guys

Have someone check your O2 sensor. My last car had the same problem when new, and after various trips to the dealer, an O2 replacement solved the problem.
