my z26 has a problem with running rough.  it only happens once in awhile but then it will come out of it and run fine.  it seems like all of a sudden it will start to miss and i cant get the rpms over 1500 without it missing.  ive already tried differnt coils and that didnt seem to help what should i try next?

Ignition module, wires, computer.
Does it happen while running after a long time?
