Honda Dealer told me a few years ago that my Crosstour was misfiring because there was a known issue with the engine. They suggested having the whole engine redone (whatever that means). Are you familiar with this? Since they redid the engine my car makes a tingling sound every time is downshifting gears. I took the car several times in a course of 2 years to the same dealer but they were never able to hear the noise.
What makes this problem better or worse?
It gets worse when car is downshifting gears.
