I have a patrol with 200,000km other day after about 5 minutes of driving I went to accelerate and it started to cough and splutter, much like running low on gas or dirty filters. It will start no problems and idle fine but will not go over 1000rpm. When you press throttle to floor it will get to 1000 rpm and start sort of missing and will not go any higher no matter how slowly you apply throttle. A diesel joint told me it has 2 faults the accelerator switch/sensor?? And the spill valve??. 2 faults they reckon I find hard to believe specially when it is followed by $4500+ bill to fix. The problem happened suddenly like a elec fault. Car has not been giving any problems till that moment had plenty power no blowing smoke. CAN ANYONE HELP HAVE YOU HEARD OF THIS SITUATION BEFORE!!!

Jason! Get a compression check on all the cylinders! 200000ks is a lot of ks for an early 3L engine . Most of them go bang at 150,000ks. Not a bad run really for that engine! Michael

Yes, I agree. Check the obvious things first. Mind you, if there is a compression problem then $4500 will look very cheap!
Best of luck.

Why on earth would a compression problem suddenly happen?
If it starts and runs ok until the problem speed is reached then it is highly unlikely it is a compression problem.

Sudden faulty running is more likely to be a blocked fuel filter and it won't pass enough fuel to run the engine past a certain load/speed. The more you try and run it the more chance of damage to the fuel system.

Had exactly that problem, had just clocked up the 200,000 ks apparently there is an electronic timing advance unit inside the injector pump, that is why it won't rev, the pump timing is not advancing. Cost me $5300.00 I had the pump overhauled while it was off, most of the cost was in the labour as half the engine bay has to be stripped to get at the pump and get it off. My advice would be to overhaul the pump while it is off whether it needs it or not because once disturbed and having done a few ks you never know how long it will last, you don't need to pay for the labour twice. My overhaul was done by a place called DIESEL SPECIALISTS in Brisbane, but the repair was done by the local Nissan dealer.

Cheers Ross.

Check your MAF sensor, get it cleaned or replace. Had a similar issue.

I had this problem once & it turned out to be a blocked exhaust. We opened it up with a air chisel & no more problems.
The only thing I had to was replace the exhaust.
No where near the cost everyone is saying
