tHANKS for the opportunity to replie .
I Tried to clean the Bosch Injectors of my 190E, 2.6L, 1988 and It was impossible. We applyed ultrasonic and special chemical, while apply more fuel rate of cleaner and pressure, the injectors was becoming more plugged.
This injectors type are a entire piece, we cant dissambled for changing filters or anything.
Please tell if there is a more effecteve way to clean these injectors.
