Engine code is M14 SCI 1800cc high pressure petrol injection - I've personally not seen one of these before (strangely neither has our local Ford dealer!)
Fault code that seems to keep re-appearing is P0092 - but does not bring on MIL light - suspect this to be an affect not cause.
Only fault I can see on verus live data is injection duration time 11 ms at idle, closed loop or open loop. As this is a lean burn engine would expect it to be less than 1 ms. Vehicle has a separate ecu to run injectors but this obviously receives signal from main ecu, low and high fuel pressure readings ok, vehicle has 3 lambda probes fitted in exhaust - 1 prefront cat and 1 after front cat then further down exhaust temp sensor and past this a nox cat with another sensor. first precat sensor 5 wire, other 2 4 wire - all readings seem ok. Can't understand what is telling ecu to command injectors on for such long duration. Vehicle runs fine for 7 miles, even with injectors at 11 ms then misfires ans begins to loose power. All other sensors test ok, MAFF and MAP etc. Everything seems to point to ECU but questioning this as instinct says ecu will only command this if it sees a lean mixture (LTFT and STFT readings seem ok)Vehicle has had new front cat and fuel filter fitted at other garage. Any thoughts about the above or any suggestions would be appreciated. Thanks Andrew
