hey bronconutt have you verified your timing yet?
before you get lost in the sensors and codes do yourself a favor and make absolutely sure you have the basics covered. i mean things like cap and rotor, wires, plugs. you get the idea. timing falls into that as well. if you moved you distributor for no reason, you have altered the mechanical order of things. the computer is probably going to have to work at correcting what youve done.
if youre serious about working on your bronco heres a few things i think you should consider buying.
1. haynes or chiltons guide.
2. quality volt/ohm meter
3. mighty vac- allows you to apply the same amount of vacuum that specific parts would see under driving conditions. (like your map sensor) you can then check voltages/resistance and make sure everything is in order. there is simply no other way to test alot of these sensors. it also allows you to make sure your vacuum actuated parts hold vacuum. makes checking vacuum lines a snap. if nothing else the ability to bleed brakes so easily will make the pump pay for itself. you can get them for 50-70 bucks= the cost of one or two sensors you didnt need.
4. timing light or at least make friends with somebody who has one.
