2007 Honda Civic Q&A

2007 Honda Civic Question: My car is idling high. When I go over 40, noise seems increases. No engine lite

The noise reminds me of a small plane as it rises higher in the sky. It is only evident while the car is in motion. I do not get an "engine light" signal or any other. This has been happening for several weeks. I keep the maintenance up-to-date. Mileage when this occurred about 100,000. Now at 102,000. Thank you -
