Hi everyone

I got my new car yesterday and i noticed a couple of times when idling it will just start adling up and down without anything being touched after a while and sometimes it will sit at around 800rpm steadily and then sometimes around 5/600. Is something wrong? or do they just have dodgy idle sensors or something cause my last 1996 series 2 gts-t didnt do it but this is a 1995 gts-t

Usually, a problem in the TPS is a constant high (around 1500 - 2000 rpm) idle. Usually caused by the sensor getting out of alignment and not sending the "throttle closed" signal to the ECU.

Variable idle is usually caused by a dirty / sticking AAC valve. That's the little cylinder on the back of the plenum chamber. It can be removed, disassembled and cleaned out with a bit of Car-B-Clean, then re-assembled and re-fitted without too much drama.

could be a vacume leak,

blind elk, thats true however my tps was out of wack in the other direction, what would happen, is it would idle fine, but you woul pull up to a stop sign, dip the clutch and the idle would **** around for a few seconds, worth checking, also the

and low speed driving was a bitch, car runs like crap, i dont think it will see 100% throttle either when you nail it

if your going to adjust idle , disconnect the brown plug on the solinoid behind it when your finished, reconnect it

Just had my 33 serviced not even a month ago, and after 3 mnths of pretty crappy idling, apparently a vacuum leak near idle starter motor was fixed, afm cleaned, tps adjusted, and timing reset.

Just last week it started ranging again from like 200-1200 rpm up and down as if i was stepping on and off the accelerator...

I have a non-oil blitz pod filter, and a blitz 3inch exhaust.

Any ideas on what else could be causing it in my particular case would be appreciated.

Cheers

    • 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.
