83 N/A won't idle
I am looking at a 83 NA that has great compression but has difficulty ideling.
Owner has replaced the following: Throttle position sensor, AFM, Chts, Fuel pressure regulator, fuel pump and filter. Car is low mileage.
Anyone had this issue? Any ideas where to start ?
Thanks
Glenn

A vacuum leak is the usual culprit. Disconnected vac line, or crack in the AFM boot, PCV / valve cover hose. Also could be: the cold start valve, air regulator, timing, or someone messed with the preset idle screws.
