Hi, my EU 328 starts fine and has normal idle. But on driving when i close trottle and open trottle again, it seems, that the engine runs with poor fuel mixture with loss of power. I had checked all vacuum lines and the engine except the injection system is just overhauled, but there are all new injectors. I anyone an idea ? What about the warm-up regulator, can this cause problems with partial load driving ? Or the fuel distributor ? Has anyone similar experiences with a 328 or injected 308 or Mondial ?
