Is your Mitsubishi Evo 7, 8, or 9 having idle issues? Surging, stalling, or rough idle when you're stopped? The throttle body air idle control valve (a stepper motor) might be failing. This is a brand new replacement unit that's fully compatible with the Mitsubishi Lancer Evolution VII, VIII, and IX models from 2001 through 2007. The brand is JCM, and it corresponds to OEM part numbers like MD628166, MD628318, and 1450A069. This little motor is crucial - it controls the amount of air that bypasses the throttle plate to maintain a smooth and steady idle speed. A faulty one can cause all sorts of drivability headaches. Swapping in this new unit can restore your Evo's smooth idle and stable rpm, making stoplights and parking lot crawls much more pleasant. It's a common wear item on these performance cars. If you're comfortable working under the hood, this is a manageable replacement that can solve a frustrating problem. Get your legendary Evo running smoothly at all rpm ranges again.
