Micro filters dod indeed solve it. Don't forget to put an inline fuel filter in place once youve changed then as it should save you haveing to do them for some time to come.

hi

really sorry to renew such a old thread but im in need of assisstance

i think SimonShogun should be able to help if hes still around

basically one of the microfilters has fallen into the high pressure pump and was wondering how you stripped this down to get it out,was it by the four bolts underneath the pump or the two on the face of it which bolts upto the head

many thanks in advance

help much appreciated

Hi

Sorry not been on here for a while.

I did indeed take he bottom off the pump and from there you can see up at least one of the channels that the microfilters sit in.

Shame, I was working in Nottingham when you posted that question and would have happily lopped over to help you out!

Hello I have a 3.5 gdi 2001 problems started when I put my foot down @4,000rpm the engine light would come on and it would stop pulling I have now got £280 less in my bank account after buying a new filler neck pipe and a In tank fuel filter, things got worse when I started the gdi it struggles @2,000rpm so today i took the inlet manifold off and held my face in my hands.

I realise now I need the high pressure fuel pump cleaned out and micro filters replacing but not sure where to get them from I'd love some help and would highly appreciate it.

Also all the inlet ports are caked in carbon and oily gunge so I may aswell take the heads off give them a good scrub do the valves,timing belt ect.

Also what kind of inline filter would one suggest to prevent micro filters clogging up again? Wink

At the top of this board there is a sticky with the part numbers for the filters and o rings. Only about £3 from mitsubishi

Manu thanks for the infos all..
just a tip to getting the filters out, I screwed a 2" wood screw partially into the filter and extracted them with pliers.

Hi all.

I'm new to this forum, found it while looking for a possible solution for a problem I have with my 2002 Pajero GDI 3.5 V6. The problem I'm having is probably the micro filters according to this thread. Although one thing I'm experiencing has not been addressed here: in 2WD the "symptoms" appear around 4.000 rpm. However, in 4WD the stumble comes much sooner, at around or above 2.000 rpm's. Has anyone else experienced that and managed to fix the problem by changing the micro filters or might I be having another problem? I know that the transfer case in my Pajero had acted up with the previous owner but that was supposedly sorted out by the dealership.

Hi, just to answer my own question, the plastic gubbins in which the scavenger pump sits in the tank IS an in-line filter and also an in-tank filter. Mitsubishi call it an in-tank filter - part number MR529135 and cost $82 from Mitzy dealer. I have not seen any mention of this filter in the forums, but it gets VERY clogged and dirty and should be replaced at the same time as the micro filter.

I've replaced the micro filter, the in-tank filter and the scavenger pump with the teabag filter. Problems all gone now and running sweet as.

Thanks to the forum, great info & lots of help. Cheers

Hi there thanks for email,i have changed every filter on my mine and still the same.My shogun the other morning wouldnt rev at all ,even with throttle down it just ticked over.It now looks like it could be the throttle pedal sensor which i am changing today so fingers crossed its that.Good luck with your probs.

Thanks for the quick reply. One question though, at what rpm does your car idle? Mine idles at about 500 rpm, just enough to keep the engine running.

Hi there again my shogun ticks over at about 800-900RPM.But when it is stood still it ticks over a bit lumpy,but when its cold its fine.The vehicle runs perfect
up to 3000rpm then its a waste of time.Have been informed by many people that these vehicles are problems and a good money burner GREAT LOL.
