Decided to put cutouts on the V, in the process I removed the RT high flow Cats. As I was putting them back on I happened to look inside and found they were melted! I had thrown a code (P0174 or P0171) a couple of time this year, cleared it and it didn't come back for a long time. Anyway I gutted the Cats tonight (B**** of a job). Anybody know where I can get the rear O2 foolers?

Rick, if you read this what, if anything, can I do with EFILIVE to fix this without screwing up your tune?

BTW I removed the resonators from the Corsa and it is loud! But it has a great rumble........ think I'll put them back on

Can't find the link right now - but there's the following:

1) Disable the MIL via the ECM

and

2) The sparkplug defowler method. I've used this and it works most of the time. Elegant and simple (a short pipe that holds the rear 02 out of the exhaust flow results in a different measurement).

I have turned the rears off on numerous gen III cars and my V following these directions. No need to extend the rears either.
