Yet another question about my vette. I beleive one or both of the cats are dying. Here is the symptons. The center console gets hot, car smells very bad when running, get worse and is getting a egg type smell. The car is a 96 with 41k miles, hot cam, 58mm TB, and program. Oh the car is a 6spd.
Yeah, sounds like your cats are dead. The smell is caused from the cats not doing their job. I don't have cats on mine and the exhaust smell funny, not too bad but it does smell different than it would with cats. :cheers:
I once in high school put some eggs under my buddies truck seat and forgot that I had played the trick on him. About 2 months later while cruising around one of them must have broke when we were horsing around. OH MY GOD! I completely forgot that I had done it and both of us thought the other one farted. But no human could smell that bad. My buddy literally puked! :lol: I was laughing so hard I about pissed my pants. Only after that did I remember putting the eggs under the seat. Man was me P.Oed. I just pretended I knew nothing. Pranks were the best back then.
Sorry about the story. But yes I think you need some new cats. You may even pick up some performance.
Cranked it up today and the car had a very gassy smell. When it gets warm there is a slight egg oder. Oh well. I'm going to be busy moving so I'll work on diagnosing it later :(
Well, I can't say for sure on the cats, but the verdict seems pretty universal that they are bad.
What I can comment on is the hot console, which may not at all be related to the bad cats. Two possible problems: 1) Lower shifter boot is not properly installed and is not sealing off shifter from area below. 2) Lower shifter boot is torn. The lower shifter boot is a real pita to install properly, even many shops will not do it right. If you've recently had a new clutch installed by a shop, chances are they didn't get the lower boot back on correctly - a very common "hot console" problem on ZF 6 speeds.
I'm gonna have to break with the crowd here and tell you to check something else first.
My old car started to have that rotten egg smell to it one time. I just KNEW it was the cat going bad that was causing the problem. I took it to a good mechanic and he told me otherwise. He said that the fuel injector (TBI) was clogged making it run lean. He replaced the fuel injector and the smell went away. So yes, technically it was the cat making that smell, but it wasn't because the cat was bad.
It also wasn't lean enough to set a code, so the car never knew. You might see if somebody can analyze the exhaust to try and figure it out before you just whack off the cat and replace it. They are not cheap you know.
