Hey Scotty, I bought a 2008 Mitsubish Lancer ES 2.0L for my son, a year later I got a code that the Injector on number 4 was not working properly. And the engine had no power to, had to rev to 4k to get the car to move out of first gear. Replaced the Injectors and the plugs, still doing the same thing. Car idles fine, and can get up to speed after a long long time, it is a manual transmission. So far after the injector replacement, car hasn't thrown any more codes yet.
