Ford: starts but stalls, mass air flow sensor, mass air flow

Question
I have a 91 Econoline 351 fuel injected that starts when cold than stalls when the gas pedal is depressed after warming up. Any ideas why?

Answer
Hi


That could bae a number of things

Does your CEL (check engine light ) operate correctly? and is it on ?

What codes are stored in the ECM?

What is the state of the tune -up? plugs, cap, rotor.

Are air and fuel filters clear?

What is the fuel pressure?

Is the coolant level up in the radiator?

Is the MAF (mass air flow) sensor dirty?
