We have been having some trouble with our 2001 Nissan Patrol. It loses power when accelerating hard from 90km/h to 100 km/h. Does anybody else have this trouble or know what it could be??

That sounds very much like a blocked fuel filter, does it also tend to loose power on hills.

Hi,
I have a 2000 4.2 patrol diesel. Recently had similar problem.
Problem solved by cleaning mesh filter on fuel pump , end of fuel line into pump.

Dean I strongly suggest that you check the tiny mesh filter that is located under the banjo fitting on your fuel pump. it is not readily seen but if you get a cotton bud and gently push in into the pump after you undo the banjo fitting you will easily remove it. Be careful you do not loose the small spring that is also in there.

As said check 1. mesh filter on fuel pump, 2. change fuel filter, 3. change air filter.
Process of elimination or just replace all. That will rule out filtration as the problem.

Could be as simple as a dirty MAF sensor. Try cleaning it with aerosol can of cleaner or contact cleaner from Jaycar. If you google nissan maf sensor there is lots of info on poor performance and cleaning
Let us know how you get on

I agree with the MAF diagnosis. Download and have read of this document from the Patrol4x4 forum. It describes your fault in detail.

I was thinking it could be a petrol also Pepper2 and then 2001 could be 4800 or 4500 - makes it prety hard to give advice without knowing even the engine type.

Ok Dean - look one thing I would say above all else is take the problem seriously , don't muck around , that car of that year is probably the most prone of all 4wd wagons to engine fail.

About that time the reports became overwhleming and Nissans first reponse was to give owners a dip stick with the oil level marked up higher so that the crank would take more oil (more splash on pistons).

From there it went downhill and today if you search around you will find much information under the heading "Anti grenading".

Its a very stressed engine with a complex control system that works really well when it works but a number of issues can cause ECU to get false info and over boost in an expensive flash.

Get it and the points others have raised here a check out and check all hoses for both leaks and particulate clogging ASAP.

I'd like to leave you with a least one positive comment and so one in our group is lovingly looked after and recently clicked over 500,000km.
