Car runs on 5 cylinders until warmed up
Took my car out of the mothballs this weekend. Idle at startup is very rough-seems to be running on 5 cyls. Wires are about 5 years old. Complete rebuild 2 years ago. After a long drive runs fine. What to check?

Have you tried the "spray a mist of water in the dark to see if there are any errand sparks from the wires?"

Yeap H2O, borrow the spray bottle from Mrs and spray a mist at the wires.
It is possible when warm the rubber expands and temporarily seals the wire/s
