"81 CJ5, 258 CI, 4 spd., runs smooth until engine partly warmed up then develops a 'miss'. Very noticable under 'load' conditions. Plugs, wires and cap replaced, no improvement. Previous owner(s) had disconnected all pollution controls. can't find a vacuum leak anywhere...help?

i don't have the answer but i must say i have the same problem... also renewed my bougies and wires but it did not work.

i don't think it's a carberator-problem but how about the ignition coil..

maybe that's it,let me know
