Sounds ignition.
Either cross induction/cross firing, coil wire, or coil.

Separate the plug wires better. Look for spots where thery've been touching together - grey marks indicate the spark's been jumping through.

Keep them as far apart as possible.

Check the coil wire ends - loose, burnt etc.

If everything else is OK, replace coil.
