Running stupid rich

[Td_d]

I had hoped never to have to post here

I've was driving home, and boosting at WOT up a hill, there was a loud squeeling sound from the bonnet, and I started running stupid rich. Went through the usual freak out, and limped home.

Car is of course bogging down severely, as AFRs are reaching the upper 9's - manages to idle fine, but on examining the logs, I can see STFT is pulling 25% fuel, getting it back to stoich. No knock, and boost was not exactly of the charts - 10psi - so I'm thinking a pipe's blown off somewhere.

Any pointers where to look?

Oh - no CEL's thrown either.

Turbo outlet?

Ok, solved. Just taken off the intercooler, came straight off the turbo outlet pipe. Fucking worm clamps... at least it's something innocuous.

Dealt. Damn, that fucking intercooler weighs a ton. AF corrections back to normal, so leak obviously sorted. Thankfully, the elbow is not chewed up. Note to self, buy t-clamps.
