Hi All,

I have read up about similar issues on the forum but still unable to locate my problem.

My stag has a miss at idle and in high rev range but not too bad though the middle I have changed coils and the car comes good for a day then back to missing again. Plugs are only 1000km old gaped to .8, new AFM. I have pulled the plugs out and the drivers side look really good but the passenger side look a bit black compared to the drivers side.

Please help, any ideas?

I started unplugging coild packs 1 by 1, passenger side no change when removing drivers side as soon as i unplug 1 the car runs ruff.

Its only running on the 3 drivers side cylinders??? WTF??

Also, check for error codes. Could be Cam pos sensor on left bank if there are no related mods like ecu piggyback, coil packs, etc.

Which plugs did you put in?

I used NGK Iridiums LFR6AIX-11 but gapped down to .8

I have checked for codes but there is nothing there...

It feels like a timing issue to me...I have swapped out the rear sensor on the left bank.

Good chance you damaged the plugs, they are too fine and brittle to gap down if you have done so.

I use LFR7aix, but a stock M35 should be fine running the hotter 6's. The plugs I use though are already gapped at .8mm, and I run mine up to 40psi without a problem on the original 14 year old coils.

Any sensor issues will be quickly picked up by the ecu and a fault light will be displayed. What the ecu doesn't know is if you plugged the coilpacks in the wrong order for example. It's very easy to mix the front plugs up, try swapping them around.

Ok swapped out the plugs to the old ones (LFR6aix-p) no change, the front 2 coil plugs can't get swapped on mine as there isn't enough length in the plug wire..... ?

On the passenger side? The rear two can be mixed up then yeh? It's the coils where the plugs sit back to back you need to worry about, I have seen them mixed up many times, sometimes it's even my fault. :P

checked again Scotty, but I was able to get any mixed up with my Stagea as the length of each plug will only go to 1 spot. I did change 3 of the spark plugs back to the old one and it seemed to make a bit of difference to the mid and top end, i will change out the other 3 this weekend coming as I don't have the car with me. I'm also replacing the PCV valve too see if that make any difference to the idle.

I have been also thinking of do an injector clean, good idea??? I'm thinking it cant hurt to do it....

If anyone else has any ideas, they would be greatly appreciated.

I can send you a refurbished set of injectors if you like, but that probably won't be the issue. You can most definitely mix up two of the plugs on each side, the ones that face each other where the plugs are nearly touching. Try it out before anything else...

I swapped over the plugs but it only just reached....you can see in the pic the front and middle are different lengths, the drivers side could get mixed up.

I'm really starting to lean towards injectors

Scotty if can pm me about the injectors you have, that would be great, unless any other ideas

ok yep, i swapped them around, no good.

i pulled the injectors, all good nice and clean, flowing nice.

i was having a listen to the exhaust and i think there might be something loose there and when the turbo comes on i can hear a different noise i havent heard before, im also using more fuel then usual, im going to have a look into the exhaust this weekend coming. could be a blocked exhaust all along.....

i love solving problems but i hope i can solve this soon cause its really giving me the shits!!! lol

      Hello, Newbie, anyone know my 32's history?

      I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.

      Hello, Newbie, anyone know my 32's history?

      By Leigh_Mack · Posted

      Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!

      2020 Nissan Skyline 400R V37/Infiniti Q50 RS insurance in NSW

      By sonicii · Posted

      As far as I know, Infiniti stopped importing vehicles before 2020, even though they were still selling their stock for at least a year or 2 after that, they were older build years, therefore, you can import a 2020 400R, because you couldn't buy an AuDM 2020 built Q50 RS. As for insurance, you might need to go through one of the enthusiast insurance companies, they tend to insure a lot more grey import models than the mainstream insurers as Duncan mentioned.

      Question about R34 GTT A/T Solenoids

      By DraftySquash · Posted

      So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.
