How do you fix a cylinder 6 misfire in 2003 Jeep Liberty?

Answer 1

It sounds like this did not start with the last plug change. I have found in the past that the "Coils on Plugs" seem to start loosing the spark about 50,000 to 65,000 miles on my Fords. It happens cause the run so hot. At least here in the Texas heat....Anyway, it sounds like you have one weak plug or one weak coil. There is a way to check these coils to find the bad ones and I'm sure someone one the web will tell you. But, I'm lazy, if I'm going in there for one coil, I will do them all and the plugs at the same time. My luck would be to have another one go bad after a week or so, so, change them all. It is always worth the investment.
