Why isn't my Civic idling properly?

My 2000 Honda Civic revs are going up and down between 1,000- and 2,000rpm while stopped. I was away for three months and the car was not used. Any idea what the problem is?

Thanks, Mark

Hi Mark,

It sounds like a sticking butterfly valve in the inlet manifold. Best solution is to clean the area with carburettor cleaner.

Let me know if that does the trick.
