Hello everyone!

If I'm coming down a hill and I let off the gas almost entirely, I sometimes
get a real loud POOF!, sometimes 2-3 times.  My exaust system does have a
couple holes in it.  It does need to be replaced...  But I suspect this
should happen at all.

I thought maybe I should check my timing.  I don't have a timing light.  But
if enough of you fine vanagon mailing list folks suggest this might be a
problem, that would be good enough reason for me to go and buy one.

My father suggests that the holes in the exhaust system are just making it
sound louder, and it's really nothing to worry about.

I just keep visualizing a backfiring that's making this poof! sound, and
putting stress on my heads.

Input?

Thanks,
