We replaced the idle air control valve last week with an OEM Mitsubishi Evo 9 idle air control valve and the car has been running great. I drove it home today and it was running good on the drive back.

With my car I have two mechanic fix it. 1 1/2 years ago the first mechanic tried 3 different aftermarket idle air control valves (2 from Import Direct which is an O'Reilly in house brand and 1 different brand) to fix a low idle issue I was having and all 3 did not work. What finally worked was an OEM Mitsubishi idle air control valve shipped from Japan.
