Did you disconnect the white connector and spray the contacts inside?
The center pin in the engine side white connector connects to the black/white wire on the TPS. Check the resistance between the center pin and the black/white wire on the TPS connector. It should be almost the same reading as you get shorting the meter leads together. If the reading is about the same, you may want to carefully scrape the pins with a jeweler's screwdriver. Then try and close up the female socket so that it fits a little tighter on the male pin.
Then recheck the resistance between the TPS connector and the black/white wire on the MAP sensor. It should be almost the same reading as you get shorting the meter leads together. Try wiggling the wires while testing them to see if the reading changes. You may need a helper to hold the meter leads in place while you wiggle the other parts and pieces.
