Hi guys!
First thread for me on this absolutely fantastic forum Have found a lot of answers to questions here but this time i have to ask. I have a 1988 HJ60 with a 2H, manual, here in Sweden. Runs great and i love it. But, it has an issue that i dont love so much - the reason for my question - When driving slow, 40-50 km/h in 4th gear, around 1400-1500 rpm on a level road (light load) just cruising along the engine starts to oscillate (right word?) It starts gently and increases fast. It is like moving the accelerator pedal up and down fast and it gets worse by itself. If i press the accelerator pedal down more or let it up i stops but comes back when return to just trying to maintain speed. Will not happen on slightly higer rpm or under more load. It feels like something that delivers fuel is moving back and forth by itself. The engine is serviced, new filters. New vacuum hoses from the intake to injection pump, no leaks. There is no lack of power, it revs fine. What do you guys think?
Have a great day!
