Ford focus ecoboost issue

[Chrispacket1152]

So today the strangest thing happened. 

I got the warning 'engine malfunction, service now' and also 'auto stop start manual restart required' 

When I removed my key from the ignition the engine continued to run and I had to stall to stop the engine running. 

 

Diagnostic threw up code p0191. 

 

Any help would be great.

I had washed the car prior to driving (incase its moisture related)

For me the engine malfunction issue was related to a vacuum hose needing replaced and the pump cleaned too. When the malfunction appears, does anything happen to the car runnung? go into limp mode or anything?

As for the code, where did you get it from? if via obd diagnotic was it not possibe to clear? (FYI The Fuel Rail Pressure (FRP) could be the isssue going by the code..Possibly)

Hi mate, 

The car appears to go into limp mode when this happens. 

The code was from obd and cleared but has since come back. 

 

Also struggling to fine a fuel pressure sensor for my car..
