I only have the 1984 model shop manual with TPS sensor adjustment. The 1983 shop manual does not have any information for adjustments.
My previous comment is not correct as I was refering to fuel injected models. Here are the procedure from our database.
1. Warm engine to normal operating temperature. Stop engine and connect tachometer. Disconnect Brown connector under air cleaner on carbon canister
side of engine.
2. Using 2 voltmeters or 12-volt, 3-watt bulbs, connect negative lead of each voltmeter to each terminal in connector. Connect positive leads to "B" terminal of alternator. See Fig. 10.
3. Start engine. Quickly decelerate engine from 3000 RPM and make sure that current flows to both voltmeters or bulbs at the same time. If current does not flow at the same time, adjust throttle sensor.
4. To adjust sensor, remove cap from adjusting screw. Adjust timing of current flowing to voltmeter "A" in Fig. 10 by turning adjusting screw. Turning screw clockwise causes current to flow earlier and turning screw counterclockwise causes current to flow later. See Fig. 11.
5. After adjustment, install cap over throttle sensor adjusting screw. Remove voltmeters and reconnect Brown connector. Remove tachometer.
Dashpot is only applicable for manual transmission, is your vehicle manual or automatic?
I am no specailist on this vehicle so my help is limited.
