Guess what.. I went on my little 20 mile "deer run" as I call it and stopped
about 1/2 as my Berg dipstick was flicking on at 45 mph.... so I go back to the
engine and I notice the air hose coming from the back of the engine to the oil
bath nozzle was disconnect.. ( might be a reason it's running hot letting the
hot air into the engine compartment) connected it then I notice that the vacuum
connection the top left of the pict 34 coming from the diaphragm of the SVDA
was not connected, so I connected it... Got in the bus , cranked it up and
drove.
The hesitation came back just like before I changed the plugs. Stopped the bus
went to the back and disconnected that hose coming from the diaphragm on the
SVDA, guess what , drove fine (as in not jerking, hesitation ) when shifting
from one gear to the next. Drove a ways disconnected and same thing (jerking
and missing like at the higher rpm's in the gears)..... Did this switch about 4
times to make sure...... now the fun part!
Stopped the bus to disconnect the hose (final experiment to get back home) got
back the bus, turned the key, nothing, no noise, got lights and radio , gauge
lights all light up, not even a murmur from the starter or solenoid. I do have
a hard start relay in it and I checked the fuse and it was blown.. no 15 amp
fuse in the bus.... bummer
out in the middle of no where (close to where I got stuck trying to chase hogs
in the other bus)....
Finally a guy came by, pushed me off, got home , (forget the cell phone too)
apologized to the wife... went out to the bus , stuck a 30 amp fuse in the hard
start relay,,,, nada... nothing.. fuse didn't blow either.... no start....
2 problems:
Why does the bus run like crap with the vacuum connected and run ok with it not
connected.,... a bad vacuum can? (not doing it's job? maybe) bad SVDA
Electrical (blew the hard start relay somehow or a ground came loose) I do know
if the hard start was blown if the started would turn over. Anyone know.
Thinking that the hard start blew along with the fuse and power is not getting
to the started....
I need a beer.....

Trey: Spark plugs are critical on the VW engine. About 9,000-10,000 miles
on a set and that's about it. I change my plugs, points and condenser every
10,000. If you have a VW engine "cutting out" i.e., missing at higher rpm on
acceleration the first suspect should be the plugs. That's not necessarily
always the problem, but is the most probable.

Sammie,
Keeping my fingers crossed. I changed the plugs (NGK) and gapped them to
.026. Drove thru the neighborhood and so far so good. No jerking when shifting
from 2nd to 3rd and 3rd to 4th. trying to talk the wife into going for a ride
but looks like we will tomorrow.
I owe you a beverage of your choice next time I see you.
Thanks,
Trey

Sounds to me like the plugs could be cutting out. That's the first thing
I would do; change the spark plugs.

Right before you shift from 2nd to 3rd and 3rd to 4th, the bus jerks at
the end of the rpm spectrum. I don't have a tach in it but at around 25 mph (in
2nd) the bus jerks then I shift to 3rd it's ok until I get ready at 35 to 40
mph shift to 4th, same thing happens, bus jerks , pulsates....
The other day on the highway it started doing this at 55 mph in 4th....
Freaked me out. I've changed the coil, spark plug wires twice and still same
symptoms. Running an SVDA with a compufire it in, could the compufire be going
out? I think these things will just fail.
I'm sure everyone is out in their buses today enjoying beautiful
weather,
I'm trying to get ready for Spicewood.
any suggestions please let me know. I did take the pict 34 off a few
weeks ago and cleaned it up, blew out all the jets and all that..Plus took the
fuel pump and cleaned the screen and installed a new fuel filter.
