I've been doing this experiment in my GT and I'm curious if anyone knows the explanation for what's happening:
- turn on your air/fuel ratio gauge
- maintain speed in 3rd gear around 3,500 RPM
- take foot off the accelerator pedal and let the engine brake
- air/fuel ratio maxes out because no fuel being consumed (ecowarrior mode on)
- as the revs drop to around 1500 RPM:
- the air/fuel ratio goes back to normal
- car feels like it is now coasting and no longer braking
My previous 2 cars had manual transmissions and were both happy to engine brake to the point of stalling the engine. Is the mustang electronically applying the throttle to avoid stalling the engine?
This is a bit weird to get used to, especially when I am planning to come to a stop at a red light and predicting that I only need, say, 3 more car lengths before clutching in and using the brake pedal - but suddenly the car starts coasting and I have to clutch in and brake early.
