Why did idle problem get better when mass air unpluged?? Cant be the sensor , ford replace that. Cant be computer , I replace that. ????Its not intermittent cause it consistantly does the same thing in almost the same amount of time every time. I have noticed that cold starts are harder than they use to be even after idle prob first started. Gotta keep stabing throttle for a while and idle never really stabilizes, i usually just start driving and idle gets better until the DREADED long stop in drive occurs then the car is never the same until it is shut off , and at least somewhat cool , and restarted and then the cycle continues.
