Could be multiple things, any other symptoms other than just the light coming on? If it comes on and she doesn't notice any differences in how the car drives, it could be anything from low oil pressure (BAD thing), engine knock (she might not notice the sound that comes with this problem) or just sensors stuffing up.

I know my HICAS light comes on a lot when driving back from Sydney, but I am 99% sure there is nothing wrong with it.

If neither of you know anything more than the fact that the light comes on occasionally, I'd recommend either taking it to somewhere like Trojan Motorsports in Mitchell, or Autotech in Hume....otherwise perhaps you should swap cars for a week and see what you think yourself, try to pick up symptoms when it happens. Stop the car and listen to the engine with the bonet up, immediately look at oil pressure, water temp, etc etc

Hope that helps a little, but unfortunately a little more info is needed :thumbsup: like trying to diagnose what someone's illness is when all the can tell you is "it hurts here" and points to themself

My wife says the engine light comes on occasionally on her r33 gtr .Any ideas what it could be?

Cheers

Small world David, I work with a friend of yours (fatz might ring a bell). Loving the vmax!

Does the engine light come on and stay on or does it flicker? Do you know if she noticed any other issues when the light comes on, like loss of power or anything?

Could be something easy and cheap or could be a warning of something more drastic waiting to occur. "Warning Will Robinson" ...lol....Sorry cant be more specific as others have mentioned what else is happening if anything. Need to diagnose and best to have someone qualified than 'hit n miss' gueses. Tuning was my issue when this light flickerd ie: knock sensor.

Your Engine light is flickeringing for a real reason in most cases - This light informs you when there is a problem anywhere in the vehicles Electronic Engine Control System. This system basically includes all sensors, solenoids, valves, actuators etc. that your vehicle needs to operate correctly. The system is big and can include both engine and/or transmission concerns.

Hook it up to a scan tool and retrieve the fault codes, may not show you the exact fault but will probably point you in the right direction.

Best way to do it is check the fault codes, write them down (reference no. and description, eg. P0205-O2 sensor open circuit), erase the codes, test drive it and recheck the codes and see which ones come back.

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
