Could I have a dreaded CAT munching V12?!!!!

[AstonExige]

Took the car to work today, on the way back about 3mins from home, I join a dual carriageway and give it a little bit of beans (not full throttle as it was cold out there) Went quite high in the revs and then the power went. From that point it went really sluggish, felt more than just limp mode. No warning lights. Pulled up at home, switched off and restarted. Engine management light came on and the car felt a little unbalanced on tickover, pretty sure its not firing on all cylinders. I plugged in my OBDII and read the codes (see below) O2 sensors picking up issues which isn't surprising if its misfiring.

So what are the thoughts? Could this be my worst nightmare? I'm hoping if it had munched one of the manifold CATS it wouldn't be so much a misfire, more sounding like a tractor as the cylinder would be damaged? Currently waiting for Aston Martin Emergency Assist to come out although I've been told none are in the area so unless I'm happy for a generic mechanic instead of an AM specialist I'll have to wait until tomorrow morning. So opting to wait for tomorrow morning!

Any news Mark?

Thanks for asking.

Works have it. Doesn't look like it was my worst fear. They think a it was something to do with the air intake, that issue caused lots of unburnt fuel to collate in the cat and it ignited. They've replaced a load of pipes and connectors around the intake and so far seems ok. They're going to test in the morning.

I'm concerned about damage to the CAT but they said cats aren't like they were years ago, they can take that??

It is all under warranty though yes ?

Yes, all warrantied until Feb 2018

Guy at HWM has been great and so has David at Works. So although the niggles have been annoying and a real inconvenience this weekend, they've handled it great.

Cars back and running great. It was a cracked intake pipe that caused incorrect fuel air mixture, made the car run like a dog and a load of unburnt fuel to collate in the car and ignite. Explains the o2 readings as well.

So nice and relieved about that one. Not quite sure what would cause a cracked pipe?

Which pipe?

The pipey looking one near the intake? No idea, I'm not exactly mechanically minded, just repeating what Works told me
