It 'could' be a fuel pressure or delivery issue ...'could' be .
and may'seem like it's not getting gas' ....
and other things can produce the same system.
a failure to want to go 'fullout' makes me think of Limp Mode.
I don't know about your Zetec engine..but some OBD-II engines will do
exactly that without a good Vehicle Speed Sensor input.
Are any codes set ?
Have you considered glogged or restricted muffler or cat .?
or thought about oxygen sensors carefully..?
if it is throttle-by-cable to you check that it gets full throttle ?
If it has a throtteposition switch ..what is the status of that part or
adjustment ?
or ..same thing for a Knock Sensor ..
and other things , including wiringand grounds.
I am under the impression that Zetec engine conversions have a direct
link to'The Vatican' ...namely Bostig .
They even flash ecu's remotely perhaps ..
of if not that, close to it.
You may notice there's seldom everanyone on this list posting, that has
a Zetec.
I figure that's because .they have zero issues ever ..
or they just arn't interested in talking about vanagon issues..
or they are tied in so directly to Bostig they do all their posting and
feeback there- with the mother ship bostig.
don't know what 'aluminm blockage' is in a fuel filter.
But I do know they have to be fairly clean, mounted in the correct
direction ..
and have suffecient fuel pressure and delivery flowing through them.
I doubt this is happening ..
more of a winter thing ....seldom ever considered even by pro's ..the
fuel itself.
99 % chance the fuel you have in it is ok..
but consider everything. I've found water in Vanagon fuel tanks, even
in summer.
Water in gasoline, while very rare ...causes odd symptomssuch as you
describe.
heck ...just a collapsing hosecan do what you are discribing.
I know a guy who spend months chasing a power problem on an engine
covnersion ..
finally he had someone look over the back seat while he drove
...collapsing hose that was under suction by the turbo.
it goes on and on .
I saw one waterboxer engine in a Westy sold by a well-known vanagon
speicalist vendor ..
The engine installer put a too-large intake boot on a smaller 1.9
throttle body..
they used a piece of radiator hose ( which will turn to goo in the
presence of heat/oil/fuel fumes etc. ) ...as an adapter piece.
By luck I happen to catch that hose laying sideways in the throttle body.
Someone could have spent hours and hours chasing a low power problem
..since it's not something one would ever expect to see.
Dig deeper !

This weekend we changed ALL the fuel lines AND installed a new fuel pump. The issue persists. At 4,000 RPM (on the gauge) the power drops as if there is not enough fuel to the motor. Climbing a hill becomes slower than ever before. Help!Geneva and MikePrescott, AZ
