Sounds like a maf failure to me....
Mine went and started as a slight missfire and no idle...
but ran so rich it coked all the plugs up.
Then the spark was too weak even to get the car to fire and start.
clean plugs and new maf and problem sorted!

I got one brand new from Japan for £150 last year. From memory my readings are around 400mv 'off' and 1100mv at idle. Maxes out at around 4v (i.e. my TD05-16G at 1.45 bar doesn't pull any more airflow than that, not that the MAF can't take any more!)
