Hi there!

So I have a 2000 Civic Si - that's about to hit the 100K mile mark.

The other day while at a light I noticed that it was idling a bit harder than normal. When I listened - it was also making some funny noises. It seems to be coming more from the driver's side of the engine??

I know its about time to change the Timing Belt and Spark Plugs I guess??? Do you think that could be the noises? Or something worse? I'm going to try and have one of my car buddies look at it - but pretty much haven't had a second to do anything. And I'm afraid to take it to the dealership and have them tell me it's going to cost $$$$$!

Help???

Thanks guys!! =D
