Spark plugs.
I recently changed my spark plugs on my 2002 ford ranger, the enging is a 2001 3.0 v6. Should I change out the ignition coil pack with he wires and spark plugs?

Coil pack should be fine, but there was a batch of faulty Factory coil packs in the early 2000's, but they should have all be swapped out by now
Spark plug wire are usually good for 10-12 years

The insulation, they start to arc on nearby metal, which reduces or eliminates spark in that cylinder
