two dead clinders at idle, but fine at higher rpm

My 151 currently idles quite rough, i know that`s a jeep thing, but mine is really rough. The strange thing is, that there is no signifcant change in rpmwhen you unplug the igniton wires from cylinder 2 and 3 . (Both have a spark). If you disconnect Nr. 1 and 4 the engine stumbles. If you increase rpm the engine smoothes out and all 4 cylinders seem to work fine. Right now i`m quite confused about the reason for these strange behaviour. Maybe the lifters fill only with increased oil pressure or do i have a vaccum leak in the manifold?

Any comments to this theory would really be appreciated

Thanks in advance

It`s getting f**ing cold in Austria right now.
