Bronco ii hesitation/stalling PLEASE HELP

Could it be the ignition stator?

Try the MAP sensor! That could be your problem!

I also have a 1988 bronco 2 as well 2.9 li 4wd automatic I have 86,000 miles and my bronco is doing the exact same thing. Did you ever find out what the problem was? Im going to get a map sensor for it tomorrow. I feel you man about your bronco. Let me know what was up I would greatly appreciate it

Tdub- yes, I found my problem. The problem was the computer. The computer sends 12 volts to the eec relay. The 12 volts from the computer would drop out for a second and then come back. The eec relay powers the fuel pump relay (among other things. Igntion.) So when the computer would drop the 12 volts to the eec relay I would lose power to the fuel pump and ignition system as well.

I figured this out by driving with a small bulb in parallel to the eec relay 12 volt power from the computer. Every time the bronco would hesitate, the bulb would flicker- telling me I was losing power to the bulb and relay. Instead of replacing the computer, I cut the wire to the eec relay and spliced it with a switched 12 volts.
Hope this helps.
