JEEP GRAND CHEROKEE SPARK PROBLEM

1999 Jeep Grand Cherokee • 150,000 miles

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.

If it didn't do that before hand, I would venture to say that there is a bad connection somewhere, Check all the sparkplug wires and boots.
