Around one month ago I have replaced my spark plugs and respective wiring. Everything was fine to until one week before, when the car started to misfire (struggle?) in the morning when car is cold. I checked the wires right after starting the vehicle and I felt electrical shocks, so I guess the wires are arcing. When I run about 5 kms, the problem goes away. The question is: what should I do to make it run smoothly from the start? I guess it might be caused by accumulation of the moisture during night(since it is parked outside).
The car is Mitsubishi Lancer 1.3 GLX '99.
