Ford Repair: 86 bronco 2, wes skiles, spark plug wire

Question
QUESTION: i have an 86 bronc 2,with 6 cylinder,4 speed,with OD, and just yesterday,it left me stranded twice..

it starts very smoothly,and normally runs very well..

now,yesterday,after running it for around 15-20 min, it began to "choke",and lose power. i could feel it fluttering,and when i would try to give it a little gas,it was just flat,and it seemed to cause more problems when i would try to give it gas.
soon after,i ws forced to pull it over,and it was running very rough,and would not idle,chugging for gas,it seemed..
now, after about 15-20 min it started right up like all was well.. only to have it do the same thing,but thankfully,it did get me home...
i have heard some people say to look at the ignition module? is it east to spot? i've heard it is by the distributor?
as you can see,i'm not a master mechanic,but i would like to save a little,(thats all i got,a little) money..
any help would be appreciated..

ANSWER: Wes, the module is something that could cause this, however it sounds more like an ignition coil.  This can be found by tracing the center spark plug wire on the distributor to the coil.  You can get one at your local parts store for around 20 dollars.  Or, you can test your old one by using a multi-meter and testing the resistance.  The reason why I say it is a coil, is because typically when the module begins to go out, it just goes out.  Whereas, a coil will just dip in and out of the maximum amount of resistance that is needed to allow electricity to get through the coil.  I hope this helps, and if you have anymore problems or questions, then feel free to ask.   Jason

QUESTION: hey jason,
i did what you said,and bought a coil..i took it for a long ride,and so far,it seems to be running good!
i sure hope that was the proble,and i'll touch base with you tommorrow with the results..

i sure do appretiate your help....Wes..

Answer
I am glad to hear the truck is running good.  What I always do when I change the coil, to make sure everything is good, is run it very hard.  Coils usually show their true colors at high RPM's.  Keep in mind, that a brand new one can go bad almost immediately.  I had one go bad in about 20 minutes.  Take care,  Jason
