When truck is driving everything is fine, but idles very rough when stopped. This began just prior to a full tune up and has continued ever since. The intake manifold has been replaced and the injectors have been checked.

What could be causing this problem?

Our mechanic says it's normal and not to worry, but that doesn't sound right.

Thanks for your help.
