Re: P1401 Question
It definitely is a job you can do in your driveway. I expect about 3 to 4 hours doing it as fast as you are comfortable with and thoroughly cleaning. Make sure you dont use anything but Throttle Body cleaner recommended by Ford for this, because it is Teflon coated, and for a very good reason. Also, dont use RTV on anything you are taking off. It is not designed to have it. If your hands are black from touching a Vacuum hose, just replace it, its only $1/foot at oreilly's. If you can, check the wired to the DPFE, and check your EGR valve while you are at it. Might as well since you are taking them off anyway. I know they are not the problem, but judge for yourself if they will be. Clean the sensors on the throttle body too, with MAF cleaner or brake cleaner. Clean the MAF and Air Temp. Sensor with MAF cleaner since you are taking those off too. This should eliminate the problem, and for a long time. Believe me, many of us on here know this procedure well, as Ford has made us perfect it.
