Setting the TPS (throttle position sensor) implies you have made it adjustable from factory preset condition.
TO MAKE TPS ADJUSTABLE:
- Remove the TB from engine.
- Use a cut-off wheel/dremel to make a slot across both factory screws.
- Use flat-head screwdriver to remove.
- Buy 2 screws from hardware store to replace, reinstall TPS with news screws only finger tight.
- Reinstall TB onto engine and connect electrically.
SETTING TPS:
- You will set TPS to 0.45V at TB throttle closed position.
- TPS needs to be electrically connected.
- Turn key to ignition "II" position.
- Multimeter red probe (backprobe) into red w/blk strip wire at driver-side upper shock mount connector.
- Multimeter black probe on negative battery terminal.
- Multimeter set to voltage (you'll be measuring 5V max).
- With probes set, multimeter should read somewhere 0-5V.
- Loosen TPS screws, rotate until 0.45V and snug screws.
- Move onto setting base idle, then base ignition timing.
