I've tried clamping the fuel return and lambda starts switching at idle but goes very weak when rev'd. Watching fuel trim figures STFT at idle. These start at 95% and gradually drop to 80 when it then runs lean. ECU then increases the fueling back to 95% when the lambda starts switching again. Injector duration is running around 3 to 3.5 m/s with the fuel return clamp removed. Its a bit tricky as then engine won't idle smoothly. LTFT figures didn't move with the pipe clamped, still reads -100%. How much is a tatty R reg clio worth?
