My Grandpa gave me a 87 bronco II and Boy, does it run like shiz...
Here's what it does
-the idle surges , when it decides to idle
-if motor is raced up it backfires through the intake
-no power HP at all top speed of the rig is 15mph
Is it a sensor?, timing?, or fuel relate? I have know clue what to do. It has good compression (145-150)...

pull codes, they will tell you what is wrong. I would think the ignition mod on the side of the distributer but thats just me. you can take it off and take it to autozone to have it checked. just make sure they check it 2-3 times because they need to warm up before they will test bad sometimes.
71 Bronco - twin sticked, full width, 2" lift, wristed arm, lots of rust...
the last time i had a ford that did that it was a valve that came undone and was just floatin in it...but it was backfiring through the intake all the time not just when it was revved up...another thing would be check out thwe catalitc converter...if it's plugged up knock the insides out of it...er...ah...i..mean buy a new one!!!lol
buy a code reader for fords mine cost me 25 bucks at checker auto...then hook it up should be under the plastic cover over by the cilinoid follow the directions and you got codes
but if you plan to have your bronco for awhile... you might as well just buy one for 26 bucks...it is well worth it not to mention if it won't start you can't get it to autozone in the future
Yea I would start with the ignition to, pull codes.
