| 300SD pulsing RPM question
I never really beat on my old girl... Affectionaly called "black betty" But I decided it was time for an italian tune up and on my way to work I aimed for 100mph.
At 90mph the engine would pulse and not accellerate any futher. I understand these cars are speed limited by the injector pump, but I think it is limited to something over 100 mph.
Any ideas or information as to why it is doing this? |
