    I just bought a 1991 Bronco Silver Anniversary with the 5.8 engine. When first started it idles fine but if I drive it at all and then put it in Park or Neutral the RPMs jump to 1500. Occasionally it won’t give me this problem. It seems to idle fine in gear when stopped. I’ve checked the IAC...

    My bronco will only start and run with the choke completely open (it is an electric choke) and idk why but it started to do that one morning after sitting all night and it was 30 something degrees outside. The spark plugs look normal. Also I have a vacuum leak somewhere behind the dash that I...
