A 2001 Ford Excursion with a V10 engine may run too lean due to several factors, including vacuum leaks, faulty fuel injectors, a malfunctioning mass airflow sensor (MAF), or a clogged fuel filter. These issues can disrupt the air-fuel mixture, leading to insufficient fuel delivery. Additionally, problems with the engine control unit (ECU) or oxygen sensors can also contribute to a lean condition. Regular diagnostics and maintenance can help identify and resolve these issues.
Look for vacuum leaks such as a cracked, disconected or broken vacuum line(s).

It is not getting enough fuel for complete engine combustion. Check the fuel injection system.
A vacuum leak, A plugged fuel filter, A faulty fuel pump or fuel pressure regulator,
No , " regular " unleaded gasoline , 87 octane is recommended
Check your trans oil. It may be low...
If the F 150 is a computer controlled model, check the computer codes. A bad sensor can confuse the computer, causing it to mix the air/ fuel ratio to run lean. Also check the egr valve to insure that is not clogged.
Run OBD codes to check. It can be as simple as a plugged up PCV.
no. not unless you get it tuned to run on e85. im a vw tech. e85 uses about 30% more fule then gas so your car would run lean and blow up.
my 2001 ford escape sputters and carries on it doesn't want to run when it is rainy or damp out I have replaced 4 of the six coils cause they were bad so what now????
overdrive ( the overdrive gear of the transmission that allows the engine to run at a slower RPM when you are on the highway )
That would depend on how fast you are driving , what the rear end gear ratio is etc.
