I'm sure it would be quite capable of burning itself out without the need for further accellerants...
I had a phone call.... Seems the guy had time for a look today, so that's where it is. They guy has some hand-held jobbie dedicated for Japanese cars, I couldn't tell you the make 'cos I'd left my glasses at home

I couldn't see the display too well either, just enough to know the blobs were changing shape constantly. His English isn''t so good and I had to go through Goran, so it's a bit like Chinese whispers plus I don't like saying "whuh??" too often. The general points seem to be:
- When the car arrived the emissions system was completely deactivated and the engine management was chucking fuel through it like it's free.
- When we changed the lamdas and cat back in March we should have reset the whole system: clearing codes with a generic code reader or disconnecting the battery for a few hours doesn't do the job.
- It went tits up this time because the ecu was still trying to work to the original settings and threw a strop.
He then reset the ecu and the emissions system sprang to life with all measurements well within tolerances. Cool.
He reckons the 54km I drove it since the fault light came up (

) probably didn't do any damage but no guarantees. He also knew all about the overfueling issue with these and said he should be able to reprogram the ecu to stop it happening, so I've left the car with him to chalk up a few miles to see if the lights of doom reappear and have a fiddle.
Btw he also said that lots of short journeys is almost as bad for modern petrols as it is for diesels
Afterwards he took us to a workshop out the back where, under a cover, was an immaculate Yugo Zastava. Ok, and? He then opened up the bonnet to reveal the engine & transmission from a Fiat Uno turbo. It's bog standard from the outside apart from some not too wide alloys, who'd have thought it? Modified suspension, disks all round, he says it red lines in every gear and tops out at 230kph. The only time I was in a Zastava it didn't even feel safe at 30kph...
