You thought about injectors? I have a feeling you might have a sticky injector.

If it's posable (ie, you have the tools) just take the exaust off after the cat and give it a rev, it'll be loud as hell, but it'll give tell you if its the exaust side, or something else.

Timing can also play a part in the problem you described.
