Eurovan intermittenly has no power

[MrLiMBO]

Hi gang,

The old Euroturtle is giving me some trouble.  Every once in a while I take off from a light or even just driving down the road, the van is guttless.  No power.  It only happens once in a while, usually only lasts a few seconds to a minute or two.  It acts like its starving for fuel or air.



What I've done so far:  New plugs, cap and rotor (they were due). The air filter is good.  I haven't replaced the fuel filter. But I did it about 18 months ago.  Its intermitten so I think that can be ruled out.   The spark plug wires look OK, I didn't see any arcing or frayed wires.



I did hook up the van to the 5051 scan tool here at the shop and I came up with a bad O2 sensor.  Its unplugged right now.  



I also replaced the Cat last year and it does not rattle.   Any ideas?  Lets here it.

Update:  I sold the van back in May of 08.  The new owner said he had the problem fixed.  It was an oxygen sensor.  Weird.  I unplugged the O2 sensor and the problem remained, that why I dismissed it.   The new guy is happy as a clam with the van.  I kinda miss it.

I don't suppose Eurovans get Vanagon syndrome?
 There were 2 years between posts, I suppose a lot happened between them.
