I can't be sure, but it seams like the IMS failure occurred at about the same gear/rpm range where we had been experiencing the hesitation. The engine failed as we accelerated away from a stop light, probably at about 28-30 mph - this is roughly where we had the hesitiation.

The argument against this being an indicator is that I actually thought that the fuel injector cleaner had done the trick... earlier in the day the hesitation seemed to have gone away.

Has anyone else who has experienced an IMS failure had a similar experience?

Ok, thanks for this post. I had a some hesitation in First gear the other day. Now im driving around with my butt cheeks clinched waiting to catch the infamous N1 H1 IMS Failure . Great. did it feel like a complete fuel cut for just a split second?? then never happen again?
