In our 2004 MPV, we got strange engine skipping that we thought was related to driving in the rain (water intrusion into ignition system), but turns out the spark plug coils went bad. It may have only been a couple of them, but they couldn't tell exactly which ones were bad, or at least that's what the dealer said. Given a possible systemic problem, we had them all replaced. No similar problems since. This all happened at around 110K miles. When we had the coils replaced, they did the plugs at the same time. It was a essentially a more expensive tune up.

Remove the ignition coils by unscrewing them and carefully pulling them out to access the spark plugs. Use a spark plug socket and ratchet to remove the old plugs, then install the new ones with the correct gap, tightening them to the manufacturer's specifications. Finally, reattach the ignition coils and reconnect the battery terminal.
