hi, the car is 1995 E300. i've already had the injectors out and serviced with new nozzles. however the engine was still very noisey/rattley. this noise was traced to no.5 cylinder. swapped this injector with no.1 and the noise moved with it. replaced injector with a new one and noise went. though there is the same noise but quieter from the other injectors. hence i'd like to replace the 5 other old injectors with new
regards,
sam.
