Could I have a vacuum problem???
The reason I am asking about the vacuum problem is that when I use cruise control, I have to push hard on the brake to disengage cruise, where before it would take I light touch of the pedal. Here is what I have posted in other posts and what I have done. PLEASE help as we are trying to get back to Texas and that is an 1,100 mile journey and we want to get this thing right before breaking down on the side of the road.
NYC 350, SixString, and others. Well, the test on the FICM showed 48.6 when the key was turned on, then 48.2 when cranking and then 48.6 when running. Now that I have started and tested in, here is what I have found, some new symptoms. I took it on the highway and the acceleration is GREAT, but still, when I level off, I have a slight miss and then when I engage the cruise you can feel it more. So, I bring it back to house and let it idle and hit the pedal to jump it to 2500 rpms and there is a small puff of black smoke, no white. And I have also put a pry bar between the gas pedal and drivers to burn more of the fuel off, and now when I get it initially level out at 1500 rpm with the pry bar, the rpms will raise to about 1800 rpms then drop to about 1400, and it seems to cycle like this when I leave it set up like this. The reason I am trying to burn off some of this fuel is the Ford tech I had originally talked to told me that I should double the dose of the Power Services in my fuel when I filled up so I did it. But now I am wondering if this might be the problem, so I am about to go add more fuel to it as well. So, up to this point, I have replaced the fuel filters, oil & oil filter, air filter, upgraded the fuel spring to the Ford blue, checked the FICM, and replaced the batteries. How would one check the injectors if someone says it might be an injector?
