3.2 Engine Surge - Ideas??!!??

Hi - My '87 (3.2 DME) has developed a small surge/hesitation under acceleration. Usually noticed in the 2-3 shift between 3.5K and 5.5K RPMs. Happens under 1/2 to full throttle, nothing under constant speed. Varies from subtle to a small yo-yo feeling - but I notice it, and it's annoying. Have Andial chip. Could try to provide more detail about what this feels like.

A few thoughts about what's been done already (all by PO's ):

6/94 17K miles - Head temp sensor
...
9/97 50K miles - fuel hose assy
1/99 60K service - clutch, O2 sensor checked, fuel filter, plugs, dizzy cap & rotor.
7/01 65K miles - Techron

So what are the likely culprits? I was thinking O2 sensor, maybe the DME relay. Or is it just cr@ppy SoCal gas?

I'm trying to avoid the "replace this, and if that does not fix it, replace that" shade-tree mechanic process. Any thoughts appreciated.

Don
