Thanks for the reminder Lance.

Don't worry about signing up late!   Late comers... last minute joiners.... ALL WELCOME! 

In that case, count on Craig and Dolly.

Eddie has never seen anything like it before. 

I've seen something like it.

And I'm eager to see if he can come up with a cause.

I put some video on Youtube {rayodude}, see if you can find your car!

Thanks for the Easter Egg hunt.  Good of you to post the link.  ^2

I've not been able to explain it nor have it explained.

Maybe Jay's guy will sort it out.

Sometimes you can tell that a converter is clogged because you don't go any faster when you push the gas pedal. Also, there usually is a noticeable drop in gas mileage associated with a clogged catalytic converter. A partially clogged converter often acts like an engine governor, limiting the actual RPMs to a fast idle.

The above were my symptoms.  The rest did not apply.

My thought has to do with: When downshift breaking, the exhaust pops and crackles - a lot.  Maybe that's a mixture problem affecting the cats under those conditions?  I downshift often - but I've driven my two other Vipers the same way with no problems - the '96 and '01 for five years each.

Craig,
The question is what was the cause? They don't just clog for no reason. Not like you have 100k on the car. =5

Nobody has been able (willing?) to answer that question.

The second time it happened, they replaced the header and melted stuff believing that was the cause for the bad running.  Ultimately they had to go back in a replace the plugged cat.

Jay,
I'm not an expert but If the cats were clogged you should have a error code with a check engine light. I would be sure they show you proof of the clogged cats.

Hey Scott,

I'm certainly not an expert either, but I had my passenger side cat plug about two years ago and my driver side about one year ago.  No codes.  When I heard Jay's symptoms, I told Lance that it sounded like plugged cat.  It sounded exactly like what I had experienced.

The second time it happened, we were down in Coronado (on our own, no event) and limped home with a hole in the headers, melted plug wires and other miscellaneous melted goodies.

Craig and Dolly are in.  Reservations made.

Craig and Dolly will be there.

Check's in the mail.

Count on Craig and Dolly.

Lance, you meeting at Spaghettini's?

We (Craig & Dolly) are planning to go but......

Plugged up a cat (left side this time) and melted some stuff under the hood.   =17  Viper's in the shop and we hope it's fixed by the 11th.
