After driving for a few moments the glow plug light comes on and engine stalls and the rev counter sticks at whatever revs it was one . problem seems to be worst between 1500and 2000rpm. once stopped it will restart imediately also the glow plug light is flashing until i restart when it goes out until the next time it fails (usually straight away) prior to this she has been running sweetly

SOURCE: engine revs up and down

Sounds like a bad IAC motor, or a vaccuum leak, or low coolant... I would definately start with checking these things first

SOURCE: Rev counter jumps when idling and then engine cuts out

sounds like the idle speed sensor,if your rpm's are idling up and down

SOURCE: asc light comes on and engine cuts out

When your ASC light is on this is to let you know your Automatic Stability Control system is switched off press the ASC button Till light is off /ASC is on this works with your rev limiter and should stabilized your idle. If the problem persists have your throttle control unit checked as thi can trigger the ASC light as well and may also activate the ABS light if not fixed

Hi

The glow plug coming on on the Diesel Mondeo is an engine management fault indicator. The car goes into "limp mode" when this happens or in other words safety mode is triggered. This explains your loss of power.

To find the cause of this light coming on - the car will have to go on an OBD scanner at a service shop which will read the codes stored in the cars computer and give you an answer as to what is causing the fault to show.

Hope this helps - please remember to rate my answer as ratings are important to me as an expert on the site. Thank You.
