> also.    What am I in for if I do not have a digitool??

Who knows? $100's? $1000's? Hours/days/weeks of wasted time?  Disrupted
trips? Years of living in fear and uncertainty knowing hesitation will
happen again, usually at the most inconvenient time?  (BTDT).

But with a digitool, a couple of weeks from now you will have a detailed
window into the workings of your fuel injection system, and an 80% chance
of nailing the exact problem quickly, paying only what you have to (in one
case, I just had to tighten the temp II connector, but the problem would
have truncated a 6000 mile trip after 500 miles) and you'll have the
eternal piece of mind that you REALLY know what's happening
in the FI system (which has about 20 failure modes, most of which are
diagnosable by the digitool) and you'll be able to quickly identify and
solve problems sometimes even before they even start showing up in van
performance.

Build it yourself for about $50, or get one from Darrell Boehler for
about twice that, and its real value is vastly higher.
