Notes:
On vehicles whose timing advance is vacuum-regulated, the vacuum limiter prevents a sudden vacuum drop when abruptly letting off the gas pedal. Quick vacuum changes will affect timing advance and could cause backfiring when the engine goes through sudden RPM drops. Check the proper condition (and replace if necessary) the vacuum limiter if you experience engine backfires when downshifting for instance.
For the Porsche 911 Carrera 3.0 L (1976-1977) use the vacuum limiter reference 911.020063A.
