About Ford IMRC
You are cruising down the road on a beautiful day in your Ford Crown Victoria, accelerating slightly to meet the increased speed limit when your car's engine suddenly sputters, chugs, and dies. You limp your car home, run a diagnostic machine on the car's computer, read the codes, and suddenly find yourself in need of a replacement Ford IMRC. The IMRC, or intake manifold runner control, exists on certain engine types; it opens and closes the air intakes on your engine's manifold in response to your acceleration. When your Crown Vic sputtered and died on the side of the road, it was because your car's Ford IMRC was not signaling the intakes to open in response to your increased acceleration, robbing your engine of the air needed for combustion. On Ford vehicles, IMRCs exist on a number of models and engines, including the Taurus SHO and the Zetec engine found in most models of Focuses and Fusions. A vast selection of Ford IMRC modules for a variety of engine and car models exists on eBay, to get you back into the fast lane.
