backfire - ish sound problem?
Hey everyone
As this is my first full summer with my vette, I have been trying to watch, listen and maintain as I go to make sure everything is more or less running ok. I noticed a backfire sound with the first minute or two at start up that goes away shortly after. It only occurs if I give it extra gas immediately after start up - it will happen once or twice and that's it. I am not really sure if it could be the cat. converter, leaky injector or something else. Maybe it is not even a major concern (at least right now?)?
I did notice a little moisture forming on intake manifold by coolant neck and front injector on drivers side - can't really tell what it is - not much smell - could be injector neck looks dry. This could also be a different issue.
It seems to run well after so I am not sure - being this is my first vette, I am guessing it is running well?
Any thoughts or suggestions would be greatly appreciated
thanks everyone
