I bought a made by VW wiring harness that goes inbetween the AFM and the
connector that connects to the wiring harness.  Before I put it in, the
van was running great.  I put in the wiring harness, started her up and it
ran like crap.  I can rev it up and then it just cuts out and dies, revs
up cuts out and dies, etc.  I took the harness off and it ran crappy for a
few more minutes then started to run normal again.  Is there some sort of
adjustment that needs to be made when installing the Vanagon syndrome
harness?  Will the harness make things worse if the van is not already
exhibiting symptoms of vanagon syndrom?  I was attempting to install the
harness as preventive maintence in preparation for a cross country trip.

Thanks very much for any help,
