It is a system EEC IV - DCL, Ford protocol. Few low-priced teams can read it, before the Wilson Champ was sold and now there is a multi-brand like the Diagno3 that is sold in Argentina. Just as much as you can do is see data, those old ECUs do not detect many failures present in the injection components; so it is more useful to buy a vacuum gauge and some tool to look for the problem in those 3 points already written.

Hi, thanks Mangel HH, for your response, I saw that video, and what catches my attention is that although it is explanatory, it cleans everything but does not show that it works again.
Buy the car and when it was cold and it was poorly regulated, the scanner and not accuse failures, except for an overload in the throttle sensor (TPS), change the engine step by step, and the car improved, only that it remains at 2000rpm . I just want to see if you can download a software and use it as an emulator and calibrate the IAC. Apparently the ECU does not manage to calibrate, it is already a 98. That is why the possibilities that do not work well increase

Thanks JJN could you mention the way and methods to use the vacuum gauge, yesterday I was with a mechanic who is dedicated to injection systems and I advise that, to look for possible air sucks, that this model is delicate in that aspect.

I enclose basic readings of the vacuometer.
