The symptoms I'm seeing right now is that the van is hesitating when it
gets up to about 4000 rpm (sometimes even before that, particularly when
letting up on the gas). The reason I wanted to try a different ECU was for
two reasons:
* Other threads I've looked at in the archives suggest trying a known good
ECU up front, since it's an easy swap
* I had the exact same symptoms a few years ago, and it turned out to be
the ECU. Putting in a different (used) ECU completely took carte of it.
I never opened up that bad ECU, but suspect it was a case of cracked solder
joints, which apparently is a common problem with these ECU -- there's
quite a bit about that as well in the archives, including some great
instructions on how to reflow the bad solder joints. Right now I'm assuming
that my current ECU has suffered the same fate.
