there's misunderstanding going on in this situation it seems to me.
The fuel injection is CIS-E ......based on that it has a computer, and CIS
was on a lot of those jettas back then.
I just put " Bosch 0 438 101 005," into google, and see right off that it's
the Fuel Distributor.
those are expensive, and problematic, from what I gather.
whether that is 'the cause' if surging I couldn't say, not without much more
info.
I will say though.........I see SO MANY times when it's just 'little things'
......
details, adjustments, air leaks, lubricating stuck things .........etc. etc.
etc.
that are all adding up to cause an engine to not run right.
and I am not replacing parts that cost hundreds or thousands of dollars
getting vanagon engines to run right.
Actually, I see LOTS of parts that are replaced unnecessarily - I see that
going on a lot, it appears to me anyway.
I do think that CIS is more difficult to deal with, in general, than
Electronic Fuel Injection.
