<< Could be the coil pack. -allison >> Mmmm, I wouldn't think so. If it were, it would manifest itself on a more or less regular basis, not just when cold. If the CP were cracked, it would arc continually, no? Check your plug wires. Also could be a drippy injector. Run some Jectron (or Chevron Techron) thru it a time or two and see if it helps. Cheap fix, possibly... Dave 11 Sep 01 Always Remember
