Same symptoms as an intercooler hose popping off, yet they're secure.

[UofACATS]

Take off from a stop, in moderate boost, and I hear a "pop," accompanied with immediate loss of power.

I immediately mentally diagnosed it as an intercooler hose popping off, although when I pulled over they were fine.

Restarted: The idle is lumpy, idles for a bit then dies, no power, but I CAN get it to rev.

Any takers? Thanks

I had a customers car do something very similiar to what you're describing. It turns out the intercooler inlet came apart..WTF ... It was a Michigan car and was heavily corroded.

I see that your're from arizona, so corrosion isn't so likely...

However, there's still many other ways for the pressurised ducting from the turbo to the intercooler to the intake to develop leaks...

I'd give the whole system a thorough visual inspection...paying real close attention to any couplers/flexible/rubber hoses that you may have on your particular car. I've seen a couple of aftermarket hoses just split wide open...but still be securely attached at both ends.

And then, if you don't find anything visually, perform a boost leak test.

Good luck, and please let us know what you find.

Well, this was right on the money. The T-bolt clamp had busted on one side, but the coulper had not detached itself obviously like usual.

Anyways, thanks and nice work..
