I would check the rotor, since there is a resistor in the rotor that
occasionally fries itself (should be obvious by looking at it, but
measure resistance to be sure.) I had a similar problem on
our 90 van which turned out to be the rotor. Non-Bosch rotors
are alleged to fail more frequently.<br>
<br>
Also - when you adjust the timing on the pre-87 vans, I seem to recall
that you need to disconnect the idle stabilizer and plug the two
connectors together? <br>
<br>
It's been a while since I had an 84, though.<br>
<br>
I have the platinum plugs in our 90, and it runs fine, but I can imagine
that they might take more or less current to fire, so might aggrevate or
show up some other weakness in the ignition.<br>

<blockquote type=cite cite><font size=2>My '85 Vanagon has been idling
rough for a few weeks now. I found the problem being a bad spark

wire, and replaced the old worn-out Bosch spark plugs with new Bosch
Platinum plugs. It seemed to me the engine was idling a little
rougher then if I would have just kept the older plugs in, but it might
have been my imagination. </font><br>
<br>
<font size=2>I then adjusted the timing and took it out for a spin.
The problem I am having is there seems to be no power at the lower speeds
and the Van is definitely getting hotter then normal when at an
idle.</font><br>
<br>
<font size=2>So I have two theories. The first is I am doing
something wrong with the timing. The second is the spark plugs are
problematic.</font><br>
<br>
<font size=2>The timing on the van is really weird. If I set it to
the correct timing, the car idles poor and requires the use of the idle
stabilizer. If I adjust to more before TDC then recommended, the
car idles much smoother and can maintain 850 RPM even without the use of
the idle stabilizer.</font><br>
<br>
<font size=2>So what do you guys think. Should I adjust the idle to
be more BTDC for the ride home, or do you think I need to replace the
spark plugs? Or some other problem?</font><br>
<br>
<font size=2>Thanks!</font><br>
