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.

Have them check the emissions again if you can get it done for free - here
in Oregon you can, the state inspection stations will test for free.

Have someone put a scope on the ignition system.

I checked two weeks ago at a friends workshop and it was perfekt,i
checked the timing on the ignition as well.
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.
