Engine Performance problem
2002 Chevy Trailblazer 6 cyl All Wheel Drive Automatic 93000 miles
I have a 2002 Chevy Trailblazer and it started to misfire when I was driving. I hooked it up to a censor and it gave me a #2 cylinder misfire. So I changed all the spark plugs and it didn't fix it. Should I change the #2 coil pack?
