G'day,

My skyline is running terrible, stalling and struggling to restart and this ones has got me stumped. The car seems to have a rev limiter of 2500? (AFM?) it really struggles to climb revs, and many times will stall and not restart. The strangest thing is the car will run perfect for the first 5 mins then start bunnyhopping all over the place like its running out of fuel. Give it a few mm of throttle and it dies in the arse and bunnyhops.

Any help is great the only thing left is the AFM, so how can I test it?

Cheers heaps

Try taking the AFM out and cleaning it with metho or something, I usually use a gas lighter on it as well to burn the metho off -may be a bit extreme but it seems to work for the last ten years of doing it every year.

Also change your fuel filter if you have not done so.

Seems to be when it gets hot that you have the problem so that indicates maybe a water temp sensor??

Yeah thanks mate, fuel filter was changed and whole fuel system was flushed out and a new tank was put it, so at least I know it's not that.

Yeah will give the AFM a better clean this time, but it was crystal clean last time was cleaned only 2 months ago.

Will check the temp sender again

I'm sure some other poor bugger skyline owner has had this before :wub:

Cheers

Yeah iv had almost the same problem. not as extreme as what your getting though. I took my car to a few different people and no one could give me very good answers. My car seems to of fixed itself though... wierd.. hasn't happend for a few months now..

    • Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice  
    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
