Full Load Enrichment System
- Connect standard radiator pressure tester in-line between intake manifold and pressure switch on firewall. Connect dwell meter to Lambda-Sond service pick-up on electronic control unit.
- With engine running, pump up air pressure until dwell meter display reads a steady 56.0-61.0°. Air pressure reading at this point should be 2.9 psi (.20 kg/cm2 ). If reading is not to specification, replace pressure switch and re-check system.
