Hello Volks.

well after nights and nights and nights of painstaking
work and also three engines later i finally got my
vanagon running wonderfully.....and after driving down
the road for awhile on a trip of about 40 miles with a
big smile on my face something started happening.....
it started surging........when i floored it, it would
run good....then when i let off between 40-65 it would
sputter black smoke and like there was no power and so
i would floor it again......runs good getting up to
speed....then surges again.......
at low speeds it does good......but sputters....idles
good but sputters now.
this happened and it would come and go, Run great for
a week ago surge and then run good again. NOW im
having a huge problem. I accidently ran out of gas the
other day and so after getting gas the surging wont go
away. this is a list of what i have done previously
Ive
changed the roter, dist. cap., new rubbers on the
injectors, new fuel filter, new plugs, wires good, no
fuel leaks, put in some injector cleaner and octane
booster, even put in a different brain. Temp is good.
Oil is great. not getting hot or anything, so i just
dont get it.........could it be the fuel pump or the
o2 sensor...(the reason im asking this is because i
accidently messed the end of it up...forgot to put it
back in the exhaust and it drug the ground for awhile
and sort of ground off the end, I KNOW im stupid.) But
would or could that affect the symptoms im having?
i need help.
