Correct me if I'm wrong, but it seems odd that coils would cause problems solely on the front bank because each coil supplies spark to both a front and rear bank cylinder. If it was a bad coil, you'd think that you'd have problems on both the front and rear. Maybe your coils were just weak in general??
