I have an '84 fwd F150. I got it from the orig. owner. It has a fresh 300 six and a rebuilt carb (he said he took it back 5 times till they got it right).
I am looking for tech info on this carb and control system. I an not going to replace it with an earlier non-feedback type, so please do not just tell me to dump it.
I have the hanes book and have looked in the Chiltons that bridges from 65 up but need a bit more info on the truck than they have. I have looked in all the common places for shop manuals and may have found a source, maybe not.
I know what you are going through. I had a hard time getting mine to idle, I finally got it, but everynow and then it does its own thing. As long as it still runs that's all I care. When I was trying to first adjust it after the rebuild I talked with several people, they were all unfamiliar with the computer controled carb.
I have replaced O2 sensor and both temp sensors (Gauge read too low, now reads too high!). No vac leaks, and I still get 10-12 mpg and what can best be described as a "sort of miss" at idle. I need to change all the plugs wires cap etc though.
Well, I rebuilt it twice just to make sure I didn't miss something the first time. It wouldn't idle like it had a vaccuum leak. I replaced several hoses even though they didn't appear to be leaking, I replaced the intake gasket and all the gaskets under the carb including the egr spacer one. Still nothing. I finally gave up and bought a rebuilt one, I didn't even have to tocuh any of the adjustments, I just threw it on and it ran good. I still don't know if it was something inside the carb or something that was out of whack with the electronics. I was just fed up with it and wanted it to work.
