Where did you buy them at? I'm wary of anything from Amazon or eBay as they are both known to have counterfeit parts. NGKs purchased from a major auto parts chain will be the correct item, and same with Rock Auto (who ships direct from distributors). I agree--that is way too much wear for 25,000 miles. I've run standard plugs in my '97 for 75,000 miles. The electrodes got rounded off and the gap was slightly more than ideal, but never bad enough that the engine didn't run.I'm thinking that I got a set of knock-off NGK spark plugs.
2010 LX 2WD. 120k miles, has always run flawlessly, transmission fluid dump/fill with Honda brand ATF every 30k miles, which changes out about 3.5 quarts each time (counting room for a small external cooler that was installed when the car was new).
A few days ago, cruising at about 50 mph, at about 1500 rpm, the car started bucking a bit. It didn't feel like the engine. Due to the severity of what I would describe as a jolting feeling, it felt like the transmission was slipping in and out.
Didn't really know what to do, cycled the OD button on and off a few times on the shift lever. Each time, the car downshifted and rpm went up as it should. Cycling back to the normal OD on position, the car stopped exhibiting the problem and has been operating normally for the past few days since.
During the episode, the "D" indicator light on the dash stayed solid, and the engine light did not come on. Fluid looks red and normal, and is at normal level, with no leaks. Other than this incident, the transmission shifts normally and has never exhibited any problems before or since.
Has anybody had this issue?
