It'* 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'* loosing power it can be a weak spark, or lack of fuel.
