I know imrc is an heavy discussion on different forum, but I want to go a step further.
When I´m doing the KOEO test, my imrc will actuate fully open. When I´m driving, the imrc will actuate at ca 5200 rpm, not useful. I will also get code P1519. When I´m reading the explanation, it´s not suitable for my car, as I can understand.
After disconnection of the battery, it seems that I have secondaries, I can feel something at 4000 rpm. But, nothing happens at the second try.
I´ve changed the transistor to a more powerful, BDW93CFP. I don´t think the old one was faulty.
Someone wrote on this forum, that he was driving for 2 years with secondaries open. I´ve tried that too, impossible to drive, when accelerating. Possible that PCM can retard the ignition at high revs. Check http://www.accutach....layCircuit.aspx.
Can I take for sure, that my imrc is correct, according to the KOEO test? Can accutach be something for the Ford 2.5? At the end, I need a complete wire diagram, but couldn´t find anything. The Haynes is not much to have to solve my thoughts.
I´m a foreigner, but I hope you can understand thread.
