hey guys,

today i started up the 1992 r32 gts-t, its stock with boost gauge and boost controller cat back exhaust, anyways, the car idles erratically and rev limits at around 2500rpm? how do i fix this asap? i've read elsewhere it could be the AFM or soemthing? any advice or a how to fix would be much appreciated.

also before this issue began my RPM gauge would go mental and turn completely past the redline, the revs don't change just the actual gauge itself, r these issues related??

Thanks

posted a video on youtube of the problem so so you can exactly what im talking about.

Definitely sounds like AFM. Unplug it and see if the car runs the same.

Try this:

car wont run without the afm matey but yeh it definetely sounds like it they do weird things depending on how low the voltage in them has gone just get a replacement one they are pretty cheap second hand for around 100 u should find one under. u havent tinkered with anything while the car has been laying there idle?

ok so heres an update, i started it up this morning and it was fine again? wtf, it first happened while i was going through a round about in 3rd gear, got out from the round about and the gear started limiting at 2500rpm so i pulled over and while the car was rolling (still running) i gave it a rev and it fixed itself, drove it home with no issue, then the next day went to start it and it was limiting as i drove up the block it hit 2.5k rpm and started like bunny hopping so took it home, left it, started it up in the arvo was fine, no issues. then as of now, this morning, is all good again??? could the wiring be short circuiting or is my afm dying?? as of right now i just drove it and its fine...only reason i ask about the wiring is because in the 1 - 2 weeks that ive owned the car, the window reg died (replaced it), the rpm gauge goes mental and last time i touched the heater i couldn't turn it off >< lol so i had to bash it then it turned off lol...any thoughts?

There is probably a bad solder joint inside the AFM. If you have a soldering iron you can crack it open and repair it using the How To on here somewhere. If not you will have to replace it.

?? Mine starts with the AFM unpluged, but it idles at like 1300rpm and limited to 2500rpm. Have I got a vacumm leak or something?

if it won't run without the afm then you have another problem

r32's definitely will run without one, i drove about 5kms without one when my cooler pipe let go (exploded out of the car and into the bush, never saw that one again

it will run like shit though thats what i m saying but yeh sounds like it is still the afm they are so cheap to buy just try one if its not then maybe a computer fault i got a spare one here i can give u for post if u wanna try it

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
