Windstar goes out

The problem in my windstar is that when I take it to take its first laps of the day it drowns as metals and it is stopped and if it does not accelerate it goes out it already discard the gasoline filter, gasoline pump, I made complete tuning and it remains the same only does it only do it when the engine is cold and always as it dulls something I think it is the time chain but they tell me that it can be a balbula and the oxygen sensor. He took Scaner and and appeared in the first 3,000 revolutions appeared missing that they could be the wiring did the job and I am so I think that I can be a balvula or an ocxigen sensor you think?

You can have an air entrance, poor mescla means greater air than fuel, look at the ignition equal

You could have problems with the temperature sensor, that also has this type of failure, the oxygen sensors can also measure them with a tester to see if they work correctly, and apart from the leaks or air inlets that the Ocinacem Czech mentions the air flow mass meter or the clean air and test accountant sensor.
