I have noticed it over and over that my Ford Explorer 2000 EB (4.0 L SOHC) if parked for over six hours or so and the ambient temp is around 30 F or lower, when I start it, it starts normally but when I put it into gear (automatic transmission) and start to move, it stalls. I have also noticed that if I let it idle for about 30 seconds or more before I put it into gear then it does not stall.
These days the temp is well over 30 F and it is not stalling.
My understanding is that engines equipped with fuel injection do not need this kind of warm up that used be the norm for engines with carbs.
Could anyone help me understand what might be happening.
Thanks, in advance.
Matt
