Not long ago we bought a new (to us) vehicle to replace an aged commuter. We decided on a lower mileage 2003 Honda Pilot. Not long after I was coming back to work and once I put the car in park noticed that the idle was surging. It would rise and then lower over and over. I was less then thrilled, but I turned to my trusty friend the internet to a site I had recently joined – Piloteers.org. I went about searching for what might be the problem, and wouldn’t you know it there was a post from some time ago talking about it.
I made a quick request of exactly how to do it and got a good response, enough so that I performed the maintenance and got it all squared away. The steps are easy, and I think even for a mechanical novice. You’ll need a few tools and spray, but I think most people will have the tools already, the Throttle Body cleaner they may need to go get.
