Do you use TopTier fuel? Do you live in a place that changes fuel formulas for summer/winter? That could account for the difference in how acceleration feels.
There really is not a "tune up" in any modern vehicle. Our Insights only require a spark plug change at about 110,000 miles. Many here have removed the plugs ( there are 8 of them) and found them looking brand new.
I might consider putting in a factory air filter just to see if the K&N is too restrictive. Also, there is a cabin filter you can change, it is located behind the glove box.
1. So far, one at 42,000. Even at that time, the fluid was only slightly honey-colored and didn't have a burn smell to it, but I changed it anyway. I'm currently at 65,000 miles, and it seems fine on a paper towel.
2. The last software update I had was recommended by Honda via a letter. It fixed some potential issues with the IMA system.
3. I use "regular" 87-octane gasoline. I could always try filling up at another station to see if it helps, as I usually go to the same one. I live in CA, so they do change the fuel blend in the winter/summer.
Thanks for the tip about the spark plugs.
