    Yes, my experience is that you can't rely on bench testing ICMs and coils. If the Well's machine at AutoZone says the ICM is bad, it is bad. However, if it says the ICM is okay, it may or may not work. Who can put up with that? Instead, I recommend replacing them every 120,000 miles or 10 years, whichever comes first.
