Do I have to replace all six coil packs?

My check engine light is on and I had it hooked up to a computer to find out what it said was wrong. It showed that one of my coil packs is messed up. The guy who did this said that if one goes bad, I'll have to replace all six. Is that true?

Yes, it's recommended to replace all the coils at the same time -
due to age, mileage and wear considerations.

Try these on-line parts resources; www.autopartsanything.com; www.rockauto.com; www.partsgeek.com - to list only a few.

The individual ignition coils should cost no more than $12.00-$15.00 each.
These parts are easily accessible and easy to replace.

What you were told is Not True.
You can just replace the failed coil,as long as they are individual coils.
If you have a vehicle with an intake manifold that has to come off,then yes,
I would replace the ones covered by the intake & keep the good ones for the
future & other engine bank.
If you have no idea how old they are & money is not important,then change them all.
Even new ones can fail in 6 months & you should be marking a date on the new ones,
so you do not get pitched that story again.
