May I ask, did you do any testing before you replaced the icm? Why did you replace the icm?
Are there any codes? If your losing spark and injector pulse intermittently, the first thing I think about is the crank sensor. Without that signal, there is no spark or injector pulse. The crank sensor is about 20 bucks, the icm is about 100. I'm not telling you to replace anything, but, a problem with the rpm signal, I test the cheap part first.
Did you check for B+ and ground at the icm. You need to test, when the problem occurs. Yes, tracking down intermittent problems can be a pain.
