My wife has a 1998 4 cylinder that has developed a hesitation. The car starts and cruises fine, especially since it has 204,000 miles on it, but hesitates when pressing the gas pedal when idling. I'm looking for some ideas on what to check so I don't waste more time than I need to. If someone can help or you need more details, let me know either here or by e-mail.

Thanks,
Tim
