Idle Stabilizer Test
- If engine stalls or is difficult to start, disconnect plugs from idle stabilizer and check contact pins for damage. If okay, connect plugs together.
- If starting or running problems are eliminated, replace idle stabilizer. If not, connect Timing Tester (VW 1367 ) according to manufacturer's instructions.
- Engage parking brake and apply service brakes. Start engine and briefly accelerate it to 2500-3000 RPM. Let engine idle and note ignition timing. Engage 4th gear and release clutch pedal slowly. Check that ignition timing advances below 940 RPM. If not, replace idle stabilizer.
