I got a question for some of you knowledgable guys out there.
I mate of mine recently had an issue with a brand new Cat Converter that had all its 'guts' crumble and block the exhaust. When he took it back to the exhaust place to get it changed, they said Cats are very sensitive to the gasses run through them and could fail due to some of the following reasons:
1- running too lean
2- running too rich
3- Lead contaminates
I have heard of this before.
Now, in our LS1 systems, we have this over temp protection, it will richen the A/F to help cool the cats.
Does this not create a problem to try to solve another?
If you richen the mixture, there will be an incomplete burn of fuel causing the leftover fuel to go through the cats which are not good for them???
