The 4wd light in my 33 GTR is staying on and the torque gauge isn't working and it's driving me nuts. Anyone else had this problem ?

I've checked all the usual stuff, hicas level in resevoir, g sensor, no codes flashing from ecu. But I wiggled the plugs to the ecu and it will sometimes stop the light from coming on. So what could it be ? Bodgy connection or a crap earth somewhere ?

Please help !

I'm sure other people have had a similar problem - that's why there is the 'search' function. Had you searched, you would have discovered that the light is an 'error' indicator, and that AWD doesn't work (torque gauge doesn't work) in an 'error' situation.

Anyway, I remember a thread recently where the problem was caused by a loose screw floating around in the ATTESA ECU.

Clayton, don't you mean "throw"?

Haven't bled it yet, but why would it be going out after I play with the plugs to the ecu ? And when the light went out the torque gauge wasn't sure what to do and kept going up and down, that's gotta be a problem with the wiring/earth ?

I've looked and tried what others have done to fix there's.

      RB25 S2 Idles but doesn't want to rev

      The 1000ccs are side feeds but they're not currently installed, had my old factory ones in for leak testing purposes, only decided on them because front facing plenums and good top feed rail kits are out of my budget at the moment, are they really that problematic? Had a set of yellow jackets that lasted me 5 years, no real issues, only replaced them chasing this misfire issue that ended up not being ignition related 😄

      Are those 1000cc side feeds? If so, that's part of your problem. I have 1480cc and they idle at stoich on 98RON, and all the way to E85. Also your coil packs.....

      Update for the sake of closure   Ended up getting the intercooler piping all sorted, new plugs and yellow jacket coils, and she was idling mint until it warmed up while I was bleeding the cooling system. Found the misfire to be localised to cyl 3 by unplugging coilpacks, ran a compression test, that checked out, then decided to get a mate to check if that spark plug was firing out of the motor. Upon cranking it over, with the injectors disconnected, the car actually fired and ran on a couple cylinders and heaps of fuel came out the top of cyl 3 I'd say that injector's either spraying incorrectly or spraying far too much, which is fine as I'm planning on replacing them anyway I'm planning on making about 250kW on flex fuel, and have a set of 1000cc injectors from ozautosport, obviously overkill but I'm planning on building the motor and running more boost further down the line, do you reckon they'd be too big for a smooth idle on 98? Thanks for the replies gents, much appreciated

      Nice modern Hypergear high flow would be perfect.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      I'm confused. You said you want to "remove the clear coat from most panels" but it sounds like you are actually doing a full respray? Few random things to add -  If you chase the blistered paint with 120 grit, I can almost guarantee you'll chase it down to bare metal (that's fine). But if you paint the car from here, you'll have nice little indents where ever the blistered paint was. The new paint won't magically level out the low areas, you need to fill them. Which leads me to the main point I wanted to add, make sure the whole car is flat before you paint it. All those areas with blistered paint you sanded out, make sure to fill them and triple check they are flat with a block guide coat. I'd also check the whole car is flat with a large block and guide coat but yeah up to you if you want to go that far.
