Ford Escape 2001 and 2005

Friends:

I have problems with two cars, I hope someone can help me

Ford Escape 2001: In the first start of the mornings, the engine begins to vary its acceleration that has been contributing to Relay, when the temperature reaches its notice, the engine works well. The scanner tells me excess recirculation of exhaust gases. What gives me doubt is that the problem is presented only when it is cold.


Ford Escape 2005: The engine does not start, it does not reach a signal to the starter engine. The anti -theft indicator on the board ignites me in an intermittent way when I give it. I already sent the lalve to reprogramming and tell me that it is the computer that is not fine. Also medium exit and entrance voltage signs of the Switch antenna make the computer and according to the whole manual. I would very much appreciate your help

Ford Escape 2001: Yes, because it is cold, the engine needs a rich mescla to be able to leave, test disconnecting the resurer as it starts,

Ford escape2005: the computer or the recognition chip may be blocked.

Thank you very much, with the Ford Escape 2005, we are already locating a computer.

With respect to the Ford Escape 2001, I already disconnected the recirculation system many times and fails to match, as I told them, this problem only does when the engine is cold.

It accelerates and decelerates approximately 700 to 1000 rpm constantly and on the occasion it accelerates up to 1500 rpm keeping a moment to continue with the ocilacion mentioned above.

Thanks for the help, if someone can give me another idea I thank you very much

Then the IAC Czech, it is generally the biggest problem, disconnect or clean it.
