hi guys my sporting 1.1 keeps cutting out at hi speed. When i drive on the motorway at 70ish ocasionally it loses all power very very quickly drops to around 55-60 then the power comes back. the whole cutout lasts no more than 2-3 seconds. the rest of the time the car is spot on idles fine pulls really well it just seems to be when im crusing.

im quite keen to get to the bottom of it because its quite dangerous when trying to overtake.

sometimes the injector light comes on sometimes it doesnt.

the car is on 57k

thanks in advance guys
 
I'd go for sensor problem, check wiring to crank position sensor and check if the sensor itself is clean.

my SX does this too, but around 90 mph. the injection light comes on and even though my foot is flat down on the accelerator, all power is lost and the car staggers to around 70 tp 75 mph and after a while the injection light goes off and all is fine ???

Yup, the injection system doesn't like something and is reducing your power to save the engine. It could be a weakening of the mixture.
