Ford Mondeo Problem 2.0L 4 cylinders

When this cold does not present a problem, but after working it for some time 15-20 minutes, it presents the problems to keep stable in low (without accelerating), it trembles a lot, to the degree of extinguishing, I put the scanner and gave me the codes P0351 and P0352, related to the coil. Check the coil wiring and it seems well, this is the coil www.ecplaza.net/ecmarket/imageView.asp?i.../adashao/5266634.jpg ?

Data from the resistances of the coil package:
Primary 1: 1.3 OHMS
Primary 2: 1.3 OHMS
Secondary 1: 10,400 OHMS
Secondary 2: 10,540 OHMS

Additional comments:
The Failure Start DES Well, to go on the road.
The car can turn on again after it turns off.
If I accelerate a little (more than 1200 rpm), the car works well, without vibrations, the problem is presented (without accelerating).
The temperature of the antifreeze when the fault occurs is 216ºF (102ºC)
The temperature of the IAT sensor is 136ºF (58ºC)
The RPM of the engine drops to 714 (normally it is between 900-950)
the MAP is 15.9 Hg
the spark plug cables have 2 or 3 months that are changed
also I also see that you are consuming me an antifreeze, well in this case, in this case, well in this case. To locate leaks, but it perishes not having

as a final comment, the car refines a week before going to the road, changing everything (spark plugs, oil, filters), and also clean the injectors with buoy, and work well until before going on the road.

What do you recommend? What other things should I review?

I would check the IAC valve, or step by step, it controls the release and this evil has to stop the engine due to lack of air.

What do you mean by step by step?

I already clean the IAC valve and the MAP, but the problem persists, how can I try the IAC valve?, by voltage?

Karma The problem you have is the gasoline pump that happens to most of the Mondeo of that year to put a manometro and when I start to fail, it is sure that the precion is lowered and if so it is the pump in case the pump does not buy the spare spare
