Could you provide some examples of the idle issues experienced with the 2008 Mitsubishi Lancer?

Mitsubishi Lancer owners from 2008 have been reporting issues with their vehicles idling unevenly and experiencing sudden spikes in rpms. This problem has been seen in both CVT and manual transmission models. Mitsubishi has issued a Technical Service Bulletin (TSB) to handle the issue, attributing it to a computer error that necessitates reprogramming the vehicle's Engine Control Unit (ECU). Other common causes for rough idling in the Lancer include vacuum leaks arising from the idle air control valve or a dirty throttle body. Additionally, the throttle position sensor may need to be replaced in older Lancers with high mileage, causing slow or erratic idling, subpar acceleration, engine power loss, stalling, and difficulty shifting gears. The typical cost for replacing the TSB in a Mitsubishi Lancer falls within the range of $330 to $450 for parts and labor.
