Its jetted incorrectly.....has a vaccuum leak, or the carbs gummed up, or your ignition is too weak at an idle.....thats if the compression is good of course.

i had same problem on my 1999, an all it was, was 1 of the breather pipes had come off, put it back on an worked a treat, might sound daft but worth a look?
