Well yesterday I get in my car after it has been running perfectly all week, its a 1999 SVT with a 2000 SVT motor, and the check engine light is blinking. I get my code puller out and it says Cylinder 4 is misfiring. So I pop the hood and check cylinder 4's plug wire to make sure its connected to the box, it is then I noticed a small cut in the wire near the front of the motor, so I went and picked up a plug wire set but its raining pretty heavy here so I changed just cylinder 4's wire, then it ran perfect. Question is since im a car salesman and work 6 days a week 12 hours a day with an hour commute the only day I have off is sundays and its raining cats and dogs here, is it okay for me to replace just that wire and still drive the car till I have time to change the others. Is the differance in old wires on 5 of the 6 cylinders going to dangerous???

That is fine. In the older days that was common pratice, to just replace the bad wire because of the cost. The danger was the flashing light, which is a cat damaging missfire because of the raw fuel being dump into the cat. The longer you go with it like that, the more of a chance you take, that the cat could be damaged. So your good for now as long as there is no other missfires.

yeah I didnt drive it on the misfire at all and after the new wire the problem went away. No other cylinders misfiring. The wire i changed had a hole clean thru it.
