i got a mk1 caddy with a 1z with a aaz pump.
when i go wide open throttle it falls on its face 75% if the time.
to me it seems like a fuel issue but i dont know.
when it does drop off it seems like the engine cut off but it still running you just gotta let of the throttle.
could it be the fuel cut off solenoid on the injector pump going bad?

If this isn't a troll account then the problem is the 1z is a TDI engine and the AAZ pump is an IDI pump. Read the FAQ and the TDI section, search M-TDI.

its been in there for over 6 years no problem
but the past two weeks it has had hiccups

Sounds like a fuel restriction to me. my 1.6 used to do that when i had a badly plugged filter
-
i just did one but i yhink it was a generic one
it was a few months ago, and i did run out of fuel about when this started too...
i will swap it and see what happens
-
if you ran it out of fuel.. you may have dislogged some ***e in there and got it clogged up worse? Try running on a clean jerry can of diesel no filter.
-
gotcha
now that i think about it this problem didnt start til after that
thanks for the advice, i will let you know what happens...

did the two filters and nothing
it changed the k@n filter (knock off)
I think it worked

Two filters?
Your filter is an open element cone I presume? You'd get better performance with the stock air box.. rather than a dirty K&N knockoff (as can be seen).
I'd look for a stock airbox.
