Yes we have pretty hard emission checks here in Sweden, almost like in
California i think. We check the car and emissions every year. I thougt that it may be the lamda some time ago, but the emissions was perfekt in the test.

Sorry, there is no way to set the timing.

I have thougt about the fuelfilter before but i don´t think that´s it
because i can load the car with a big boggie caravan and it works fine in the range under the 3700rpm whith the gaspedal to the floor. So i tink it gets all the fuel it want´s.

What i don´t understand is why it starts to mess around at that specific rpm. If i slowly goes up to 3700 rpm with gearbox locked in position 2 the engine will stall and lack power and sligthly miss in the ignition and while it´s doing that the rpm gauge will go crazy and be all over the place. If i continue to press on the gaspedal it would miss even more and in the end start exploding in the air cleaner. If i would go about 55 m/h (90km/h)and try to accelerate so the kickdown engages, it would shift down and just blow the top of the aircleaner, belive me i tried, it blow the plastic hinges right off.
