Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I've got a catalytic converter that rattles at idle, making the car sound like crap (it runs fine, however). My indy and the dealer both acknowledge that the cat is bad, but the dealer won't change it under warranty until it triggers a CEL. They'd be happy to change it out on my nickel, which is pretty pricey. I've considered buying the part through Sunset and doing the install myself, but wanted to run it by the board. Feasible DIY job? Worth the cash? Should I just wait until the CEL comes on?

POST 2Original post

how long has it been rattling? It is only a matter of time before the CEL comes on. Did you check with another dealer to see if they'd cover it? If the part is bad, it should be replaced under the emissions warranty without problems (just had mine replaced again in October). I'd hate to see them invalidate your emissions warranty by you installing the cat yourself. Steve

POST 6Original post

Patrick, A very simple DIY job. Just think of it...the money you save on labor can go towards other mods.

if he waits for the CEL to come on (should be soon) he won't have to spend ANY $$ as it's a warranty issue.

POST 9Original post

The dealer should replace it for nada. Be patient Grasshopper...a free new cat is in your future.
