allot of 3lt d22's have that problem almost always its the heat switch which is connected to a neutral switch on the gearbox, disconnect it at the gear box and away you go problem fixed. I had it happen to my old d22 and i just unplugged it and left it that way, i never had the problem again and didn't miss the heat switch one bit.
If you do a search you will find a heap of other people who have had this problem. you will probably even find how to locate the switch at the gearbox.
here is a link to an old thread about this problem http://www.navara.asia/d22-engine/782-2004-d22-surging-2nd-3rd-gear.html
and another http://www.navara.asia/d22-engine/10006-d22-surging-problem.html
One more on how to find the neutral switch http://www.navara.asia/d22-engine/7407-engine-studders-under-load.html
As i said before if you have any probs do a search for d22 neutral switch there are pages of info.
Hope that helps.

$5K for checking injectors is a rip off. You can replace them for about $2K, even less if you DIY. Are you sure your mech wasn't talking about the injector pump (even then $5k is excessive)?
Try the heat switch first. Then find a new mechanic!

The heat switch, is just a high idle switch.
But it cuts out when you engage a gear (any gear). The neutral position switch is what signals it. I don't why it affects the power, I'm not that smart.
You're problem is what I had, though not as bad, by sounds of it.
You undo all the trim and bolts around the gear sticks, ( or get at it easy enough from underneath...)and you'll find 2 sensors on the right side of the gerbox, one with a black cover boot, and the blue one, which is the NPS. Just disconnect the plug, and take it for a quick spin, you'll know straight away....
If so, order a replacement from Nissan.

I was told by a diesel mechanic to just disconnect it and leave it disconnected which i did and never had any issues in over 150,000km after it was gone. So i wouldn't even bother buying a new one. I go down the snow allot in winter and never needed the heat switch once, But its up to you.

Excuse my ignorance. But what does it mean to "surge"?

Basically the best way i could describe it is, when you are accelerating the power is no longer consistent, and comes in waves or bursts. You have power then it dies away and comes back.

Like hitting the rev limiter in a petrol and the ECM shuts the injectors off.

I always wanted a hardtop U12 Bluebird.
They have all been butchered now though.
Finding a un-modified one is near impossible.
Any pics of the GTIR.
Oh and a N15 Jap spec would be cool. SR16VE goodness.

They only went into the GT X-Trail's though.
I wish Nissan would just turbo the QR series engine.
