Hi,

I have a 99 Civic CX with 46k on it. When the car is warmed up and I'm stopped at the lights I can hear a kind of a knocking sound coming from the engine bay. It only happens when the tranny is in gear. It's an automatic. When I change it to Neutral or Park the knocking sound goes away. It's not very lound but I can hear it every day.I went to a dealer and they told me this was normal. I could hear this knocking since the car was almost new.

I looked at another 99 civic at another dealer lot and the knocking sound isn't there.

Any suggestions? Does your Civic Automatic make this knocking sound when in gear?
