95 jeep cherokee country

I wanted to change the spark plugs and wires. Does this engine have a distributor cap and rotor if it does should i replace it if so is it hard to replace?

It depends...how many miles total..and when was the last time they were changed.

Get a basic manual and it will tell you what to look for as far as wear is concerned.

IMO...there is two approaches...

*change everthing...cause eventually you will need it
*go cheap...change what you need now....but...ultimately...you will need the cap and rotor ..etc....later....
