My IMRC has been broken since last fall; I pulled it out in late November and have been driving around with it removed up until yesterday, 8/4/2012. The only reason I replaced it is because I was sick of looking at the Check Engine light on the dash. But I wanted to comment that since I replaced it yesterday, and have put over 100 miles highway miles on it and another 20-30 city miles, I don't notice any difference, other than the Check Engine light isn't on anymore. It doesn't feel anymore responsive at high or low speeds or rpms. Hopefully I notice my mpg increase, because I did notice a dip of about 4mpg when it stopped working. We will see. Did anyone else notice little to no difference when there IMRC wasn't functioning?
