Connect a voltmeter between the signal and signal return line on the TPS and slowly sweep and check for a dead spot or fluctuating voltage.
Also check for a vacuum leak, a central vacuum leak will create your high idle condition and may be causing your throttle problem depending on the circuit that is being affected.
You will have to check the plastic lines carefully for a crack/break.
