Hello Mark
I have now removed intake manifold and cleaned swirl flaps, fitted new map sensor due to carbon contamination.
smoke test carried out no leaks present in exhaust or vac/intake system.Injector duration time still 11ms at idle.LTFT has now altered to 45% and vehicle drops out of closed loop.suspected pre cat oxy sensor(wideband 5 wires)but has been changed by another garage(genuine ford),also front cat.Main ecu must control front wideband sensor internally. strangely emission are not out as you would expect.
Everthing points to ecu faulty program.
Ford main dealer and techhelp line unable to tell me weather ecu update available or current version is correct.(calib1d01 bosch relveh14)ecuid se8 cvn 01 c8668dfo.
Any help with this appreciated.
Will try to upload some screen shots from verus.
regards Andrew.
