Personally I'd disconnect the battery positive lead for 30 seconds or so then reconnect and start the car and let the ecu re learn the idle again and see what happens.
Good suggestion. After my HG fix, she wouldn’t idle. The shop said they had to teach her how to be an RS again. My mind won’t let me imagine what that lesson was like.Personally I'd disconnect the battery positive lead for 30 seconds or so then reconnect and start the car and let the ecu re learn the idle again and see what happens.
For sure. You can get IDS in the UK as a DIY/end user, but the subscription is £3k plus the equipment annoyingly.I really wish that Ford would let the vehicle owners have an IDS license. It seems that there are lots of diagnostics through that that are not available to standard OBD dataloggers. In addition to what you found, I think per cylinder misfires would also be handy to see.
Replaced fuel filter, no change. Will suggest vapor canister itself/injectors. I'm a strong believer it could be something to do with the vapour cannister though... Seems to be worse when the tank is low and a lot of sloshing of fuel has happened
Did it work?Further update. Finally got a datalog that Ford technical could read. HPFP pressure readings within parameter range but a bit a bit low. Suspect some kind of leak internal to it. Slight smell of petrol around the area of it. Ford recommending new HPFP. Getting this done on the 12th. Fingers crossed that solves the issue.
