so I swapped a fuel inj. 5.0 in place of the 289 in my cj6. The motor came out of a 88 Lincoln mkV11......speed density, ran great...all cylinders around 165-170. I used the old harness to begin with, couldn't get it to run right so bought a modifyed harness and computer from a outfit in San Bernadino . I can't get this thing to run right! It idles roughly, bumping from 800 rpm down to stalling. On the road it misses badly, especially over 2200rpm's.........I've tested the TPS, and the idle air bypass, it's timed correctly and can't find anything that even hints at a vacuum leak.........it has a rebuilt NAPA dizzy so the stator and TFI are new....... any ideas are welcome....I'm stumped Jim S.
