John,

slip a question into the Patrol Forum. Someone will know what's going on.

Cheers. Mick

just a thought , brake light adjustment?? In my auto I use left foot for braking and found if I still had the brake lights on when merging the fuel was cut to idle (embarrassing). Thinking if its a bit rough and the brake lights are set a bit hair trigger it may be cutting fuel, just a thought...silverback

Hi John M,
Did you find out what the problem was with your Patrol. I am experiencing something similar, mine is due for a major service soon and is still under extended warranty.

John

Your issue will be the air flow sensor, I'll put a $1 on it. Have you got an original air filter or after market job? Anything other than original Nissan air cleaners in these is a BIG no no.

Even if you haven't, your issue sounds very familiar to others I have seen.

If you have no luck trying other suggestions...go straight into Nissan and get a new a AFS, ASAP!

Good luck.

we have fitted 100s and 100s of non genuine air filters to 3ltr partols never seen a air flow sensor stuff up because of type of air filter
infact last air flow meter we replaced actually had nissan filter.

I think Andrew means after market oiled foam type filters, apparently the oil contaminates the MAS.

hi andrew, pitty you didn't put more money on bet, all air flow components and the air were serviced and replaced last week including the filter (original nissan one) thank you for taking the time to respond with your advice....regards john

Mate, I thought it was common knowledge but obviously not. And like you say, it even happens with the original air filters but filters that require oiling really stuff up the MAFS. (in my experience)

If you haven't experienced this type of thing, no worries.

I have however, seen it many times and it happened to me.

I was merely stating my suggestion based on experience to help the guy resolve the issue asking the question. Be it right or wrong.

I'm just glad I only lost $1

While on the subject of non genuine filters, if you go to repco or anywhere like that and ask for an airfilter for a 3.0 patrol you will not be given the right one!

The filter you will be given is simply a dry paper element filter (grey in colour) and the correct one for the 3.0 patrol is a cilicon coated paper element (red in colour).

I have had several disputes with mechanics about it because of problems I had while in the Kimberley in 2003 and the car had been fitted with the wrong filter. The MAFS was compromised by dust getting past the filter.

Muzz,

You are very correct! The dry paper elements still let through particles that sand balst the MAF.

Hi John, there was question on here the other day/week about a similiar thing. Im not sure wether it was related to the 3 litre or the 4.2 or might even be a later model patrol but was some thing to do with the accelerator pedal and some switch on it. Cost them $799 to fix as you had to buy the complete accelerator pedal assembly. I might be totally incorrect and sure some one will say if I am. I will do a search and see if I can find it. Regards Steve M

Found it thread no 56483. "Here was the question"
Hi all i am a new member so bare with me ...no profile yet.
Here is some advise to all out there that own a 2003 GU Patrol....... I have owned mine for only 3 months bought it with 60,000kms on the clock, i had a problem with quick acceleration the patrol would not respond and die down to idle revs, didnt matter what gear or at what speed if i hit the throttle quick it would not respond without completely getting off the accelerator and the of course changing down a gear or two,,,,very dangerous in some situations, like roundabouts for example, so for you people out there that could be having the same problem, it is the " pedal position sensor" which requires a completely new pedal kit with a small cost of $700.00. Hope this might help someone out there

Sorry John, didn't even look at who posted it, Di@khead me. Glad you fixed it anyway, nothing worse then an intermittent fault. Regards Steve M

What about the fuel filter? Have you changed it recently? If not, then maybe a good idea to do so. If yes, then check that it is tightly done up. If there is ANY chance of air getting sucked in, then it will.

Also, did you have plenty of fuel in the tank? If it was under a quarter of a tank, then it is possible that you were not getting enough fuel once you started the ascent as the fuel surged away from the pick-up point in the tank.

I'm a great believer in having a secondary electric (Facet) fuel pump fitted to ensure you get a positive fuel delivery (of course this won't fix up the issue of low fuel level in the tank).

Good luck, Roachie

thank you ever so much for your replies and advice but i regards to the problem, after spending all day at nissan the head mechanic admits there is a problem but cannot say what it is, they sent all diagnostic data to nissan australia for advice and a possible solution answer in 24 hours but this could be a design falt as nissan (my local dealership) tested 3 other vehicles,the same model as mine and they also have the same problem, so at this stage we don't know what we are facing but at least it will be warranty work,thats what they(nissan) say.
i will post the findings when i have them hopefully tomorrow night

take care john
