Why does my car rev up at a stop sign?
When I am stopped at a stoplight or stop sign, my car’s engine unexpectedly revs up. If I put it in neutral or park, it subsides. It happens only occasionally, sometimes months apart. I have reported this to Honda on two occasions, and have brought it in for a testing procedure. Both test sequences came up with nothing. I don’t know what to do.

Why does my car stop when I put it in Park?
If I go with the first method, shifting back into drive, right when I put it in park again it continues to do it and wont stop unless the engine is shut down, which feels terrible. It also will idle low and rough when its in park and not revving up as I said before.
What happens when you shift from Park to drive?

Do you put the car in reverse when the engine is not idle?
As I said in my previous response, don’t ever put the car in drive/reverse while the engine is not at idle. As for your problem, it may be that you have a leaky or clogged PCV valve. It could also be a problem with the idle setting in your ECU, since it only happens when you’re in park/neutral. – Samuel Perron Nov 12 ’18 at 16:21
Do you have to Rev the engine to charge the battery?
Yes, revving your engine will charge your battery, but not all the time. Generally, the car system ensures the battery is charged at all times. However, significantly discharged batteries will require you to rev the engine to provide some charge. Commonly used lead-acid batteries will usually be charged when the alternator is running.
