I would like to assure him that there is no need for him to worry about his idle. It is only natural that his idle stays around 500. In my case the idle normally is in the range of 500 to 700. When I showed it to a mechanic he told me that it is perfectly normal and that I need not worry about it.

I would check for vaccum leaks especially at the breather hoses-I had one a bit loose and the car would not start at all. I read that one must always check for air leaks and in my case that was perhaps the best advice i have received. A vacuum leak does not have to have a raised idle if there is too much air. Consider what happens when the car sucks in too much air and not able to compensate by adding fuel...It stalls.
