I have a 2010 Camaro V6/RS. I don't drive it much, b/c I do alot of traveling. I noticed the other day a strange ticking sound coming from the engine when it is started. I took it to the dealer, and they said that was the fuel injector making the noise. Is this true? I haven't heard it before. Also, when I click on the Recycle Air button, you can hear the mechanism opening and closing. I never heard this before also. Is all this normal? Any help would be appreciated. Thanks!
