Any thoughts or ideas on this one. Sierra 1.6 OHC engine. Ticks over and revs perfectly, but any attempt to move car and revs die. Just no power. Its probably a coincidence but started doing this the day after it MOT. This car has never let me down before. I've cleaned up all the plugs and set the gaps, but get the feeling this is a fuel problem and not ignition. Doesn't misfire, just looses power.

Does it have the truly vile VV carburettor? If you think it's a fuel problem it'd help us no end if we knew what fuel system it has!
Had exactly those symptoms on a Renault 21. Set of new plug leads cured it. DaveK.
during the MOT maybe they adjusted the CO mixture and now its too lean?
Just had a look in book as had no idea what make carb it was and its the Weber.
It did drive ok for about 20 miles after MOT before fault showed. HT leads are nearly new and there is a good spark on all plugs too.
As I say it doesn't misfire at all and runs perfectly smoothly at tick over and any revs, not lumpy at all. Just no power to move it.
Thanks for suggestions so far.
Diesel in it? check cam and ign timing. air pipe fallen off, blocked exhaust. rag in air inlet. blocked fuel filter leading to low fuel level in carb

Check the diaphragm.
I've been told that faulty HT leads can be diagnosed quite well in the dark.

Took me ages to find out what was wrong with the wife's car one day. It was only as it was getting dark that I saw the blue glow all over the ignition system that the penny dropped.
