Ok guys, I was trying to fix an oil leak lastnight, I changed my turbo return hose for some nice speed flow fittings and a braided hose, unfortunately I still didn't get it....haha

But to the main problem, I took the car for a quick lap around the block to see if I fixed my oil leak and gave it a boot full as it only leaks at high rpm or when it's on boost, and after I backed off and put in the clutch to roll back up out the front the car suddenly was stuck revving at 4000rpm, I quickly popped the bonnet and checked it wasn't the throttle stuck open for some reason but it wasn't it, could the tps be stuck in a position telling the computer it's still open?

Car has a single throttle body, running a motec computer, not running a afm

It's never done this before and I didn't fiddle or disconnect anything while changing the oil return

Does it have idle air control valve like stock ones? If it wasn't single throttle body it would be the seals only other possibility is u blew a intake manifold gasket? Get some brake cleaner and spray around the inlet manifold while running and see if idle changes.

I don't think it has one anymore, I'll try start it now to see if its had a change of heart today and pull the plug on the tps see if it changes

I killed the power from the battery so hopefully its reset the computer if the motec had a fit

If not ill try find some brake cleaner and give it a spray

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
