Another vote for AFM. My car has the same problem and I used a consult cable to diagnose.

A reasonable way to check (that helped me) was to leave the engine running, then press your finger onto the AFM plug. One of mine was fine, the other one almost caused the car to stall.

After reading the post about how the plugs are simply soldered to the PCB, perhaps me pressing down was unhelpful...? :)

id say spark or fuel hahaha u need both for the car to run*duuuuh

without taking it for a drive, the first things i would check would be

coilpacks/ignition loom /ignitor & plugs

DOUBT it would be fuel related but if it is it sounds electrical, not like ablockage i.e. fuel lines/filter.

a dodgy sensor would do it i.e. AFM - may even be boost cut related?

hard to tell, with what mods have been done to the car etc. but yeh the things that everyone mention are definitely the most common. Id start with the ignition side of things.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
