European adventures in a 200 turbo

[Richard van der Hoff]

The more we think about this the more a weak spark matches the symptoms. 
The question becomes, then, how to figure out which bit of the ignition 
system is the problem, and what to do about it - given we're in a random 
bit of Eastern Europe where the (F)LAPS are unlikely to stock 
distributor caps, rotors, coils and ht leads for 1980s 5-cylinder audis...

We'll pull the plugs tomorrow morning to see how they look. We've also 
got a spare set of leads (no king lead though) and a dizzy cap, which we 
might swap in - but they're used, and not known-good.

Suggestions welcome!

The situation is that we seem to be low on power - most noticeably, the engine won't rev above 4000rpm in top gear. It seems anaemic in other gears too, though the auto box makes it a bit hard to tell :). Backing off the throttle actually gives more power and it will rev higher. There's also a smell of fuel, as though it's running rich.
