[s-cars] Stumbling at low rpm

[Peter Schulz]

Vincent:

The flux will eventually migrate towards the O2 sensor, contaminating it, or the environment will activate the flux and lead to corrosion of the splice.

BTW, I disagree with the practice of solder splicing wires, especially in an underhood environment

I worked for a defense contractor for 10 years on Navy systems. The US Navy does NOT allow soldered wire connections.

They only allow wire-wrapped connections or calibrated crimped connections, which need to pass a conductor pull test.
The crimpers are calibrated and are similar to the ones with removable dies (about $30 bux at electronics stores)
Bentley/Audi recommend the dies that crimp the connector into a "w" - curl on both sides.

Think about the ocean environment - salt - humidity, moisture....then about the underhood car environment.

Unless you can completely remove residual flux from the connection, this environment will lead to corrosion and failure of the soldered connection.
