Full Throttle Enrichment
- Connect Dwell Meter (VW 1367) to vehicle. Using Adapter Cable (US 1112) connect Green test lead to OXS system test connector (Blue/Black wire). Set "%" button on duty meter.
- Disconnect vacuum hose going to ECU. Remove throttle switch. Start and allow engine to idle. Bridge throttle switch terminals No. 2 and 3. Ensure that duty meter indicates a constant 60% duty cycle. If not, check continuity of throttle switch wiring back to ECU.
