well, i drove my car down the street (you cant really go that fast or boost enough to see), but its stumbling, it struggles to idle if you rev it. It bogs then goes back up to 1500 then back down to almost the point of stalling, then it will settle back to 1000.

Sounds like what mine is doing. Are you getting a code 42 (always rich)? I am right now trying to track it down.

I bet it has nothing to do with fuel pressure / ignition or cam timing / intake leak like just about EVERY other post made about stumbling problems.
