Sounds like the ECU must be faulty if the injector duration is only 3.0-3.5 ms with the STFT at 95%, but if the lambda is switching, perhaps the fuel trim readings are similar to the Rovers where 100% is normal & therefore 95% is only actually + or - 5% & the drop to 80% when the fuel return is clamped is actually reducing the fuelling as it should. Sorry to confuse matters, but somebody else must have come across the strange fuel trim readings on Rovers etc. Could it be worth checking the gas readings before the cat? Regards,Andrew
