Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Had a misfire in cylinder 3, changed plugs and wires and then coil pack. Now van is backfiring during acceleration. Could the wires be on in the wrong order?

Most likely they are crossed! OLD COIL PACK IS NUMBERED, look at it!! Now, looking at the enging while standing in front of van, the cylinders back near the windshield are,1-2-3 from your left to your right. ------The cylinders up front near you are 4-5-6 from your left to your right! Put them on the new coil pack at the proper position according to the old 'numbered' coil pack!
