V36 Missing Hessitation?

Hi All.

I have an 07 V36 (VQ35HR) and I think I have a very minor miss. When accelerating lightly usually uphill or hard acceleration I can feel an ever so slight sense that the power is not smooth and I can only describe this like a miss. There is still plenty of power but the delivery feels like it could be smoother. Before I go changing plugs ($100 for set of iridium's) could there be anything else to look at?

I have data scan but not really sure how to us it to identify this sort of issue (assuming there are no code issues).

Thanks.

Just change the plugs, good chance they are flogged, or the previous owner skimped on them.

Gives you a good chance to clean the coilpacks and check the rocker gasket isn't leaking into the plug tubes.

Got the spark plugs and off I went to replace them. Even got a new socket to fit as is has a 14mm hex which is tiny. So started on the passenger side and could only remove one plug. The socket seemed to be slipping of the hex. I though maybe the socket was too thick so I ground down the outside of the socket thinking it was fouling on the outside of the plug hole. Still no luck. So I stopped and put it all back together again. I have only replace one plug and didn't bother on the driver side as I'm sure I will have the same problem. I didn't want to strip the spark plug, thinking I'll have to take it to the mechanic and spend $200 on labour unless someone here can help.

Is there a special tool for this job that only Nissan has? Has anyone had this problem before.

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
