Ignition Timing: VANAGON
- Engine oil temperature must be 176° F (80° C). Connect timing light and tachometer. Start engine and allow to idle. Check ignition timing at 800-1000 RPM.NOTE: Before checking engine timing, raise engine speed above 2100 RPM at least 4 times. This must be done each time ignition is turned off and restarted to clear ECU memory and by-pass hot-start, fast-idle function.
- If an adjustment is needed, turn ignition off and loosen distributor hold-down bolt just enough to move distributor by hand. Remove connectors from idle stabilizer by squeezing connectors then pulling apart. Plug idle stabilizer connectors together.
- Start and allow engine to idle. Turn distributor until notch on V-belt pulley matches separation in case. Set timing and RPM. Reconnect electrical connectors to idle stabilizer. Tighten distributor clamp bolt.
