Im having some issuse regarding my idle.It hunts between 1100 and 1600rpm.Ive tried many things to fix it.New plugs,cleaning the ACC but nothing seems to work.Some people have said it might be my TPS(throttle position sensor)

How do i get it reset?

Help me solve my problem as its been like this for 2 weeks now and is driving me crazy.

The TPS is your throttle position sensor. Im not quite sure what you mean by does this mean i dont have a throttle cable? Because of cause it has a throttle cable going to the throttlebody to open and close the butterfly. The tps is used to monitor the postion of the throttle. Take the TPS off and give the end a clean its possible that it could be giving you grief. Have you tried cleaning your AFM aswell?

afm clean: use electrical contact cleaner... p.s i wouldnt be pulling the tps off, its set to a specific point, very important it stays there unless you mark it perfectly. tried cleaning your throttle body? for that you can use carby clean. also tried resetting your ecu?

OK ive pulled the AFM off and found that there is a film of oil all around the inside of it.Seeing as its oil i cleaned it out with degreaser and is drying in the sun.will fit it in 10 and tell you the verdict.

How the hell are you getting blow by, if there is no point for the engine to dump oil into before the air flow meter?

It goes, POD filter, AFM, normally then recirc line pretty close in (From BOV), then turbo...

I don't understand how you claim blow by as the cause?

When you cleaned the air valve, did it have a HEAP of crap built up in it? (Black carbon) and when you finished did it all look nice and new?

The rocker cover breathers plumb back into the intake pipe in front of the turbo. It doesn't dump it in before the AFM it just gets a residue there and the oil builds up to a pool. I have removed a few intake pipes that have a good 20-30ml of oil in them when the turbo has been completely fine.

And has it been built up in the AFM...

Remember, the air is being sucked from air filter, to afm, to breather pipe, to turbo...

It's not going backwards.

And the AFM sits higher then where the breather pipes join, so it can't "run" there when cold.

When the turbo reverts air, it bounces back and forth between the air filter and compressor wheel. This is how it gets there.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
