I had an '85 Jeep Wagoneer LTD that did this. Only in that case I had
to turn the ignition off, let it sit for a while - then turn it back on,
and it would run fine until the next episode. The fix for that turned
out to be a new ECU.
In this current van, I've never had this particular problem that worked
just like this. I have had roughness to develop, and simple
disconnection of the O2 sensor took care of the problem. I had that
problem on both my '85 GL with the 1.9L WBX, and this current '88 GL
with the 2.1L WBX. .But never, ever have I experienced this gradual
increase in roughness, only to clear it with a simply turn off/turn on
of the ignition.
Of course, all this leads me to the question - what is the cause of the
Vanagon Syndrome, exactly?? I thought the 1.9L engines were the ones
that suffered the problem. So what do I know?
I'll research this, but it would be nice to get a short answer to that
question.
