My wagon has a problem fuel i think when i step down on the peddle it starves for fuel but when i take my foot of and just give it about 1/4 gas it picks back up again,not much fun when you can only drive with the peddle 1/4 of the way down through gears it also does a similar thing if i tighten the fuel cap right up.She is a ea82t td04,vl turbo injectors and fuel pump,intercooler if that helps???.

Have you checked the fuel pickup line? Do you have a problem on flat surface? (Ive heard this problem but cannot remember what it is, it has been a thread about it in here a while ago..)

She does it on flat surface and up hills, i think i will put the old ea82t injectors back in it today change the fillter, blow air through all fuel line and maybe take the tank of and give it a clean out and if this does not fix the problem i will buy a new fuel pump as old one is pretty old.

Ok i pulled the tank out today,pulled out the injectors,fuel pump,filter and fuel regulator. Blown out all the lines with compressed air,fuel pump looks pretty old so going to buy a new one $80 for new vl turbo pump ebay getting injectors checked and cleaned tomorrow, new filter, i have a new adjustable malpassi fuel regulator i will put in instead of the old stock subie one, does anyone no what presser i set the regulator to for the vl injectors? hopefully with all that done, pretty much a new fuel system this surging problem will go away.

In the past if I find AFM which has a problem, best way is to swap it over to another one to see if there is any difference.
If AFM was faulty you would find stalling problems or jerking feel while driving.
