I left my '87 vanagon idleing for about 45 minutes, (very talkative
customer).  After I drove off it started hesitating and lower speeds.  It
seems to get better and worse at times.  Today as I got off the freeway,
(4000 RPM's for about 35 minutes were no help cleaning off the plugs), the
problem reoccured as I drove away from the freeway at a slower speed.  I took
out the spark plugs and they were all burned, gray ashy.  I wanted to replace
them, (Bosch) but all my local auto parts store had in stock were autolite
platinum.  The van seems to accelerate a bit better but the hesitation is
worse than ever!  HELP!!!!
