1983 - 95 Ford Bronco F150 Check Engine Codes

Where to start with the Bronco? She is currently running a little rougher than a 351 down one cylinder should be, so lets see what the computer has to say!
In this video we cover the process for pulling KOER (Key On Engine Off) OBD1 engine codes. This process will vary slightly depending on year and model, but will work for all Ford EEC-IV ECM vehicles. Certain models continued to use 2 digit codes into 93 while other models started using 3 digit codes in 90.
