mercedes hymermobil engine problem
Hi, i am new on this forum and need help.1 Months ago i buy motorhome mercedes hymer-mobil, engine om616, 240D only 93000miles. And it is made from van 307D year 1979. when i buy car, engine runs very bad, shaking, lot of smoke unstable idle and slow speed only 37mph. Injector was worn so i replace all nozzles. Replace all filter, fuel hoses and oil. And last with drip method set injector pump. Now engine runs smooth, not shaking and when gets hot not smoke at all. But problem is speed it goes only 45mph. Acceleration on 1-3 speed is good but 4 speed. I try auxilary fuel pump and add shim under diaphgram spring, nothing help. Any advise?
Sorry for language i am from Slovakia
