Oh Yes, one other thing ndolsongtp that I though about that may be causing the idle problems:
After I cleaned and rebuilt my car's intake and fixed the injector problem, I was having idling problems and getting really bad gas mileage. It ended up being a vacuum leak at the point where the two vacuum lines that come from the braking system hook up to the upper intake manifold. The plastic retainers had broken apart and there was not a good seal.
I went to local Ford dealership and bought the replacement hardware (came with gasket, plastic retainer, and brass fittings) and just replaced the gaskets and retainers. Problem solved!
The point is to do your best to make sure the are no leaks after the mass air flow meter, or else the computer will think you have less air going into the engine than what you really do. This can cause some problems (including too lean)
Let us know how it all goes!!
