2008 Honda Fit Hatchback, automatic 250000 miles
When the gear is in drive, Rev count goes up and down like the car will shut itself. When it is not doing this. Let's say it is in neutral gear, when I go to drive or reverse, the Rev count goes up and within a minute it will drop again to normal.
One last problem is that this car sometimes cut and stop when I change gear in this way, I'll be reversing and when I hit brakes to change gear, after I uplift my foot it stops and I have to start it again.
Help me with this problems
