- Throttle valve switch should start to operate when throttle valve is opened 2 degrees from its normally closed position.
- To adjust throttle valve switch use Tester (0684100202) on BMW, Tester (EFAW 228S 10) on Renault. Use manufacturer's instructions on tester for correct switch positions.
- Readings on tester should indicate zero resistance at idle, infinity at part throttle, and zero resistance at full throttle. If not, loosen throttle switch screws.
- Rotate throttle switch clockwise until needle on tester moves from an infinity reading to a zero reading, then rotate throttle switch counterclockwise one graduation (2 degrees). Tighten throttle valve switch and check for proper operation.
NOTE:
On 1978 BMW 733i, the angle between idle cut-in position and idle stop on switch should be 4.5 degrees. Full throttle angle, between idle stop and full throttle cut-in, should be 62 degrees.
