Generally the code refers to: P1634 throttle valve adaptation test failed. Not knowing your vehicle type I cannot be mroe specific.

My generic BMW list show that code as
P1634 Throttle Valve Adaptation; Spring Test Failed

If you decide that a cleaning might help, don't force the throttle valve open with the power off. Plug it in and have someone turn on the key and press the gas pedal so you can spray cleaner on it while it is open.
