slight stumble at WOT and rpm drop?

[sick GN]

I have a slight stumble that is at WOT, it is kinda in stages, like 2 or 3 individual stumbles. Also at idle in park the rpm's keep dropping on their own. It seems OK then the rpm's drop about 200rpm's then it comes back. Before it wouldn't idle smooth and it was really fast idle. I set the IAC and TPS but the idle seemed too low so I turned up the idle adjuster screw. Any suggestions would be greatly appreciated.

Thanks

I know my stumble ended up being a collapsed fuel sock. It was a good time to change to a walbro.
