87 B2000 high idle
New here. I bought this truck yesterday. It was a cool day (50) and it started fine and ran well during my "test drive". After driving it home (80 miles), I noticed that it idles at about 1100-1200 and won't settle below that. I tried "tapping" the throttle, but no change. I'm not familiar with this engine/fuel delivery system or what would be the possible cause(s). I entend to check all vacuum lines, but aside from that I don't have other ideas. Any thoughts would be appreciated

I think that your truck has a carburetor with electronic choke. You should remove the air filter cover and check that the choke is opening completely when warm. If not, it could be a problem with corroded wiring connectors, bad heater element or binding choke linkage. These carbs also have a fast idle detent to speed engine warm up after a cold start. You should check to make sure that the linkage on this is not binding.
