A week ago, I changed my spark plugs and boots on my Jeep. I noticed the next day while driving that it idled really rough and sputtered some. It did the same thing when I was on the freeway and had the gas pedel about 1/4 to 1/2 down. I took off the coil pack and checked for good connection as well.
