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.

What is the engine size? 3.0?

Replace the spark plug wires. This is fairly common symptom when they are
defective . At the vehicle's age I'd bet on this being the cause of your
backfiring.

Done that...twice!! and plugs.
First with aftermarket cables,now original wires and new plugs for
about 40$(295SEK) a piece. Not cheap but will stay in the car for the
next 3-4 years and thats nice.We all know how much fun it is to cange
plugs on this car ;-)

Does any Chrysler mechanic out there know if somthing special happens
in that rpm range (3700-4000rpm). If extra fuel is added or if
ignition timing is radically changed or something like that????.
Could the problem be a faulty computer unit??.
And why does it sometime work perfectly, it has nothing to do with
weather conditions dry/wet/hot or cold.
