? Miss Fire ?

[doctorDHD@xxxx]

Today I noticed that the hunting my D has at idle seems to follow a 
particular pattern. At idle, my tachometer jumps up a hundred rpm or so for a split 
second and drops back to "normal idle" (during this time the engine has no 
perceivable change in speed) , then the engine revs and drops back to idle speed. 
Sometimes the tach jumps once prior to this cycle and sometimes it jumps 2, 3 
or 4 times. The higher the number of jumps, the higher and longer is the rev. 
Is this diagnostic of anything?
