Hi there!

Ours is a 2003 Odyssey with about 65,000 miles on the clock.

Lately is has shown some trouble climbing a long grade, which is more or less steep. In the past the minivan has had no trouble there, but as of two or three weeks ago, it feels slow climbing and is sort of shudders, like if it had a dirty spark plug.

On flat streets it also feels kind of slow. I've also noticed that the transmission shifts a little bit hard among the gears.

Because of traffic conditions it seldom shifts to 4th, let alone 5th gear.

Thanks in advance for the advise.

Spark Plugs?

Have you changed your spark plugs yet?

I've changed ours twice ('03 EX with 113K) so far, and I can always tell when it's due when performance starts to lag exactly as you described (especially around 60K miles).

If you haven't changed your plugs, make sure to do so first.....This is one of those service items that you can notice by the seat of your pants right away. I've always used NGK PZFR5F-11 plugs.

...Don't forget to use anti-seize on your plug threads & always ignore the factory plug service interval of 105K miles
