Today I diagnosed a late vanagon. Complaint was high idle. I verified
compression, fuel pressure and regulator, temp sensors, AFM, plugs, vacuum
leaks. Only thing I found not in spec was spark plug wear. Oxy was fluxing
nicely but plugs were black with carbon and I could smell over rich. Found
a crack in one of the exhaust pipes. Unmetered oxygen getting sucked into
the exhaust was registered by the oxy sensor and telling the computer too
lean, so the computer was giving the injectors too much fuel.
