Wife had a late 90s Accord a few years back. Not sure why, but that thing was rough on plugs. 10-12k and it would start running like crap. Replace plugs, good or another 10k or so. Old plugs looked fine, but something caused them to misfire. Expensive plugs, cheap ones, all shades in between...no difference.
At least it was a 4 so they were easy to get at.

That sounds precisely like coil problems.

I just changed the plugs on my E450 V10. That was fun! Not!

I used to love those. Take coil off with a 24" 1/4" extension and a swivel 7mm then 2 Matco 3/8" impact swivels and a 10" extension for the plugs. The impossible becomes profitable.

I used to take plugs out and put them in with a air ratchet too.....

Never f'ed one up.

While plugs may last a lot longer than years ago it is still wise to periodically remove them too make sure they are not frozen in their threaded sockets. Porsche for instance has a mileage and or time requirement for replacement and it is for the reason mentioned above

Every set I install gets anti seize on the threads.

Sounds like a good reason not to mess with them! :)

The new Iridium plugs say use no antiseize, just torque correctly
The plugs are supposedly inherently antiseize. I guess we'll know in 20 or 30 years.
