Hello everyone

I have a R34 GTT and It has those 3 light on

I just replaced the coil pack and spark plugs but still the same problem

The car does not accelerate normally, the engine sound ok at low rpms

Reading at some post...some people fixed with an new AFM

Does anyone here have an AFM I can borrow or buy?

Thanks

try cleaning the afm first as it might have a light film of oil over it from blow by from the PCV system

If you know its a faulty AFM there are a few people wrecking r34's in the private sale section otherwise go to skyline spares in wetheril park.. cheapest place for parts and a top bloke

Could also be the coilpack loom, or an off chance that it's a faulty coilpack or plug. Have heard of both.

Actually heard a similar story to this a while ago and it turned out to be a fautty new plug! Hope it's something simple mate.

When you floor it above 4.5k rpm what does the boost get to? I thought mine was normal till I found out 12 psi isn't normal lol. Should be round 7-8psi, or round 0.5 kg/cm^2 which I think is the unit on the gauge.

Would be surprised if the gap was the issue on the 0.8 gapped plugs.

I think it is getting better

Got an airflow cleaner from Repco

and I can drive the car now and it feel ok, Thanks David

But I still have 2 lights on TCS and SLP

I have disconnected the battery for 24 hours to reset the ECO (Does it work?)

after the 24 hours the lights still on

I have a boost controller and I havent figured it out yet..may need to take it to someone who knows and can show me how it work

The factory boost gauge doesnt work..can it be because of the boost controller..taking the reading?

Thanks everyone

If the lights are coming on after a reset then it's a new fault code. You can detect the fault codes using this

but I'm guessing it's the usual ones. You can also reset using that above, which is way easier than playing with the battery.

Are you sure everything was plugged back in after the plugs and coilpacks were changed?

The boost controller may be the cause of some of these problems. Did you install it yourself?

All the light are off

Thanks everyone...I think the problems was the AFM, after cleaning it and a proper reset...(Disconnected the battery and pressed the brake pedal)

Everything seen to be working

@Galois

The Boost controller came with the car..and no instruction manual ..I need to find out how to use it..

Thanks again to everyone for your opinions

i recently cleaned my afm inside and out with electrical cleaner and in the process cracked a few dry solder joins and had your same problems,

was stressing for a few days because i thought i toasted it with electrical cleaner some how then found that, like my boost gauge sender device, the joints were cracked.

i think its a common problem for these particular joints to crack and open circuit because ive seen alot of people with this problem on the forums.

resoldered them and all is well :)

sorry im a bit late to post :P

Yes.. I saw this link in how to fix it

I will try to fix it and if it works I will have a spare one for the future

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
