Replaced plug one at a time correctly, and now van is driving worse then before. what would cause this. It is backfiring, and doesn't want to stay started.... need firing order, to verify correct order, some kind of info...
98 v6 3.0 engine.
If you find that the firing order is correct, then be sure to check all the plug wires. I found that its just easiest to install new plug wires and be sure to use dielectric grease on both ends. Could also have not put the plug wires on the plugs all the way. This is very easy to do on the back plugs
Did u check to make sure they were gap correctly they should be a 5.0
