What are some of the 2008 mitsubishi lancer idle problems?

Owners of the 2008 Mitsubishi Lancer report their vehicles idling unevenly and experiencing sudden jumps in rpms. The event has been reported for both CVT and manual transmissions. Mitsubishi issued a TSB to address the problem, citing a computer error that required the re-progRamming of the vehicle's ECU. Other common reasons why the Lancer may idle roughly include vacuum leaks stemming from the idle air control valve or a d***y throttle body. The throttle position sensor often needs replacement on high mileage Lancers as well and will generate a slow or uneven idle, poor acceleration, a loss of engine power, stalling and the inability to upshift. The average cost of replacing the TBS in a Mitsubishi Lancer ranges from $330-$450 in parts and labor.
