<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>A further update to my problem. Turns out the bad distributor harness wiring, while truly frightening, was not the cause of this problem I was having. Driving it the following day revealed the problem was still there, and getting worse.<br></div><div><br></div><div>I downloaded the Digifant troubleshooting pages following a link on VanCafe, discovering later they're also in my Bentley. Ran through the tests, checks and adjustments to find my Throttle Position Switch not closing when the throttle closed. First checked via human ear, then with VOM. Adjusted and retested to ensure switch closure with throttle. Not clear if something wore out of adjustment or what there, I have not touched it previously in a few years of ownership.<br></div><div><br></div><div>Next day (yesterday) driving revealed no symptoms. I'm not 100% sure of this fix yet, but compared to the night before (had to pull over twice because of the problem) it's 100% better at least. Will report back later today.<br></div><div><br></div><div>Gregory Smith<br><span style="font-family:Verdana;font-size:10pt" mce_style="font-family:Verdana;font-size:10pt"><div><div>'88 Vanagon GL<br> '77 Lancia Scorpion<br></div></div><div>Olympia, WA USA</div></span></div><blockquote id="replyBlockquote" webmail="1" style="border-left: 2px solid blue; margin-left: 8px; padding-left: 8px; font-size:10pt; color:black; font-family:verdana;"><div id="wmQuoteWrapper"><div class="gmail_extra"><div class="gmail_quote">On Sun, Nov 17, 2013 at 1:50 PM, Gregory Smith <span dir="ltr"><<a href="mailto:gfs@gregoryfsmith.com" target="_blank">gfs@gregoryfsmith.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><span style="font-size:10pt;font-family:Verdana"><div>Glad to report I think I found the problem.
