Topic: P1687????? Urgent!!!!

[rcherb]

Has anyone ever gotten this code combined with a p0123? I've replaced the TPS, plugs, wires, cap, and rotor. Fuel pressure is good and so are all the injectors.  Is this a sign of a bad computer? Please help, I do not want to take it to a dealership

Do your guages ever go dead?  Do you ever get a NO BUS message on the odometer?
