Sick Scooby, help please!

Driving happily along today, all was fine until..

CEL comes on, car sounds and feels like it's running on 3 cylinders and to top it off - there's smoke from behind the turbo Turbo knackered?

I wasn't pushing on either, this happened in town traffic of Westerham - had to limp back to Beckenham, which I hope hasn't done any further damage! I'll also add that I never rag the car, bit of boost every now and then, but always treat it with respect.

It's recently had a plugs/filter/oil service.

I've been aware of a few little niggles it's had and maybe they're related? Upon starting the engine, it would sometimes run lumpy, until I pull away and then all would be fine. I've always put that down to a MAF issue.

Last week, it did seem to hiccup and misfire - that disappeared however.

Any comments welcome!

EDIT - The car is an '02 WRX.

Thanks for the reply - don't know the CEL code yet, and yeah was looking at readers - think I need to get hold of one.

It's more the fact this has occurred as well as the smoke behind the turbo that's concerned me - could it coincidence that two problems appeared at once? Or could that be connected? Not sure how though, if it is a sensor issue.
