Full Throttle Enrichment

  1. Using Adapter Cable (US 1112), connect Green test lead to OXS system test connector (Blue/Black wire). Connect Dwell Meter (VW 1367) to vehicle. Set the "%" button on dwell meter.
  2. Disconnect vacuum hose going to ECU (if equipped). Remove throttle switch connector. Start engine. Bridge throttle switch terminals No. 2 and No. 3. Ensure dwell meter indicates a constant 60% duty cycle. If reading on dwell meter is not as specified, repair circuit between throttle switch and ECU.
