Hi

Was yours Problem 1, Stalling when engine speed dragged too low, or Problem 2, Engine stopping at speed?

Problem 2. I would be driving along at 50+ mph typically, and the engine would cut out on light or medium acceleration, but would only happen intermittently. Didn’t happen at low speed at all. Very frightning on new smart motorways as it didn’t even drop to limp mode so you had to stop in a live lane, then restart your car, then it would be fine again until the next random event, (could be 5 or 50 miles later, who knows!!).

great that you have found a fix for this issue. ive been watching to see if anyone sorted it before my next Mondeo had the same problem.

I am pretty sure that if a Diesel engine stops it is fuel related.

 

Compression and fuel is how they work?

 

Cutting the fuel is how they have to be stopped?

 

Unless someone has reinvented it.

Hi

With modern electronics they probably have!

The electronics involved will be to efficiently control the fuel supply and air quality for emissions standards.

 

If it has air and fuel it won't stop.

 

Stopping the fuel will still be how the engine is switched off.

Hi

Although my post above regarding modern electronics was a little tongue in cheek, the Diesel engine is now a lot more refined and complicated than the older mechanical pumped compression ignition variants.

No doubt any sensor not receiving the correct information may now just stop everything.

This has been happening to me every 2000 miles for the past 9 months. but its not rev related. I have an auto 180hp and it just cuts out whilst normal driving at 70mph. usually whilst on cruise control. been into dealers 6 times and had loads of bits changed but still no fix. it always happens just as I apply a light throttle and then as if by magic the engine dies. No fault found, no code and Ford don't have a monitoring device that records so no luck. getting to the point where I need to get rid of the car. Dash just shows a nice picture of a spanner with the comment "see manual".

restarts fine after you have coasted into the slow lane then to a stop. put it in park, turn off. Ive had a failure in the Dartford tunnel and on the M25 with no hard shoulder at night in the rain so its a bit scary.

Hi Colin. Did you find it what was the problem with your car?

i sold the car as Ford couldn't fix it. the best prognosis since would be leaky injectors. if id have taken it to a specilist they could have checked as Ford wouldnt.

 

However i was looking to change so i did.
