Hi guys i am new to broncos. bought it a couple weeks ago but it has no power and glitches i guess you could say at low speeds. I have done a complete tune up replaced tps replaced coil fuel filter and am at the point where i just would rather swap the motor in from the 90 f150 in. the bronco is an 87 with a 302 as well. Now my question is how much changing around would be involved or is it a direct swap? Do I use the old ecm and harness or do those got to be swapped as well? Also the f150 is 4sp and 4x4 how much work would be involved in putting the 4sp in the bko that is an auto? Any help would be greatly appreciated.
