Truck will run for about 35 to 40 seconds after starts then dies. Upon restart the same thing happens unless you override the dying by accelrating. Will not continue to run on its own. Have replaced spark plugs and spark plug wiring, coil checks good. Ran code and got the message that it is the maf or volume air flow circuit, low input. Is this the problem or could it be the fuel injectors? The truck does cut out at highway speed but does not die all the time and runs rough.
