Just wondering if any-1 can shed any light on this for me :D

sometimes randomly out of the blue when i turn my car on or while ill be driving it will drop RPM slightly the TCS and SLIP light will come on also i think it's the ECU light (lil square orange light on the top right hand side of the dash cluster) and it will start to idle/run weird sounds like it has dropped a CYL sound basically sounds like a WRX. Have checked/replaced coils and it only does it some times, it might not do it for a month or so then it will do it again :S

please help :laugh:

Do a self diagnostic test on it by bridging two terminals on the data link connector there is info on here somewhere as to how to do it, bridge CHK and IGN with the ignition on, mil light will most likely flash a code 21 = no consecutive ignition signal with engine running meaning coil pack.

thanks heaps :D it's just got me stumped as it only does it some times :S if i tried the self diagnostic when it was running normal would this still show the same problem as to when it was running crappy ?

    • And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.
    • Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....

    • Nah, lots of insurance repairs on V36 and V37 for pedestrians deployments. Reasons ranging from possums, to extremely severe potholes have deployed them. However, paying for the full repair can still be upto $5k AU some people have noted!
    • Hi, i got 1998 r34 4 door auto abs model and its manual converted with bigbox when i bought it . I successfully find the neutral and reverse light wire but can’t find the speed signal wires for speedo drive. I know its grey plug but on my loom no grey plug with 2 wires . I opened the loom upto where it getting branch with other wire, i’m amazed they is no wire. So need help how to fix the speedometer problem. I search on google it says some r34 model measure speed from diff sensor. Is it right? I talk to a wrecker he say no this isn’t right, i’m kinda stuck. Please help
