Answer
Roberto: Have you had your computer tested? The computer controls everything in your car, it has not be reading the manifold motor temp right. Because everything is not ok, I would get that checked. You know don't you that the building of those computers were farmed out to another company and for the most part some of those computers are not good. So try that. How old is your oxygen sensor might have that checked too. I pulled these ideas out of my repair manual. So hope this helps you and good luck!
