Diagnostics, especially on older cars, often involves much more than just reading the trouble codes and replacing the obvious component. There may be multiple factors contributing to the currently reported issue and often there are other issues that should be attended to at the same time.

This leads to more diagnostic time spent checking stuff just to verify those things are not also causing trouble, or about to cause trouble.
