Loss of power in 3rd gear

[Patrol Girl]

Hi,
I have a 2001 GU ll 3.0ltr Diesel,manual.
I have just replaced the glow plugs and cleaned the MAF using MAF cleaner and now when driving either up hill or on flat road 3rd gear will not go past 2.5 rev just stays at same out put until I change into fourth gear. All other gears are fine. Any help/advise please.

Won't be anything to do with glow plugs but possibly the MAF sensor , was it like that before you cleaned the sensor?
And what did you clean it with ?

I also think it is the MAF Sensor itself ... they are fairly fragile, and don't like being disturbed too much.

There are certain voltages it should be outputting. See this thread for voltages http://www.nissanpatrol.com.au/forum...ng-MAF-sensors

If you have another I would swap it out to check

Delicate little suckers , I cleaned mine with a can of Inox spray lube and $270 bucks later it was working just fine .

Sorry should have added don't clean the sensor with spray lube of anytype .

Somethings are just better off not being touched haha. So today so far no lack of power in 3rd gear go figure, I am still concerned as something has to be amiss somewhere. So might get a new MAF just in case, check all the hoses are not crimped or loose. I have to put a new Idler pulley joy joy.

Having a spare MAF sensor and belt tensioner is just part of owning one of these patrols but the go anywhere nature of them outweighs any negatives .
