It's possible the ICM is doing something to your coils. If one has gone out again, make a note if that one is the same one that went bad last time

Well I replaced the battery for a good one,. It was weak and I assumed it may be causing a problem. The car still seems to bag out between 80kmph and 100kmph unless I really get into her and pin it out. Any range that isn't that, works well. Frustration mobile! Heh!

Did you ever check your fuel pressure? If it feels like it's loosing power it can be a weak spark, or lack of fuel.
