1989 Ford Escort
My Ford Escort runs fine down the highway but afterwards stop idles ruff, blows black smoke out exhaust pipe. I have installed new plugs, wires, and an oxygen sensor.

  1. The black smoke is an indication of a Engine running RICH condition. This could be caused by different things. The running rough is happening because of the running rich condition. The best approach would be to extract any computer codes that might be able to point us in the right direction. The good news is that you can do it yourself at home without a scan tool. Post any codes below.
