bad ignition coils?

my 98 z28 has been acting a little sick lately.
went down to autozone, and they pulled the codes.
they found the B, D, F, and H ignition coils all came back with codes.
is it pretty conclusive that I need to replace them?
is it worth the time to swap those with the other 4 and see if the codes follow them?
anything else I need to check before I replace them?
do I need to replace all 8 at a time?
are the MSD blaster coils worth the extra money?
(this car has over 180,000 miles, so I'm thinking I'll probably go as cheap as possible.)
where's the best place to buy the coils?
thanks
(lol, that was a few more questions than I expected)

Yes, best to swap the coils to see what happens.

BTW, I'd look at the plugs and wires first.

I would say if you have to replace that many, I would go with the MSD blaster coils(8). There has been some mixed reviews in the past but I know of 3 users that just installed them and are very happy.

If you don't have a ton of mods, I wouldn't spent the extra money on the MSDs. I would just replace the plugs and wires with aftermarket and compare the price difference between stock and the MSD coils.

It could possible be the coils w/ the mileage but id check the plugs and wires first.
Also did you see the codes say bad coil or did the guy tell you that, I work at a parts store and you would be suprised how dumb some people can be who work at those places. Yesterday someone I work with tried telling a customer the reason her car wouldnt start was b/c her car needed antifreeze

Thanks for the help guys.

Yeah, I did actually see the codes for the coils come up.
But I haven't had the time to try swapping them yet.

I read somewhere the coils on the 98 were installed slightly differently than in other years.
Is this true?
Any good link for install instructions? (I tried installuniversity.com with no luck)
