KE-Jetronic causes and errors - rough engine running

The KE-Jetronic, developed by Bosch as the successor to the K-Jetronic, has been expanded to include electronic components (control units) and guarantees continuous electronic injection. In this video, the individual components of the KE-Jetronic are explained, and the causes of a poor starting ratio and/or fluctuating idle speeds are explained.
Nevertheless, the KE-Jetronic is considered to be one of the most insensitive injection systems available.
The KE-Jetronic is used in the Mercedes models R107, W124, W126, W201.
