Continuous Misfire Issue??
3.0L V6 12V
So my car started misfiring in one of the cylinders, so I tuned up my car to replace the spark plugs and the wires since i have not done that for years.
The car ran fine for a week, but then started misfiring in the 6th cylinder. I then bought a new coil pack, however that did not do anything as my 6th cylinder was still misfiring. I then changed my 6th cylinder spark plug thinking maybe it cracked when i put it in, and it actually fixed it.
However, 2 weeks later, I am getting a 5th cylinder misfire. Why is this happening?? Should I now replace the 5th spark plug, even though it was replaced a month ago? I do not want to be constantly changing/buying spark plugs.
