bring it to the workshop near ur place. if u in mt gravatt i knw a good mechanic around there which is near the JB HIFI. i used to work there. is locate in front of the pool n snooker shop. if u knw where.

Did u check the coil packs see is it burn ? i think i had tis kind of problem before in my work place's customer's car. but is R33. yea i just hate the hicas light alway on and off.

but , if is about the idle. pull the coil packs n check whether is burn or not. if im not wrong one of my customer's car had tis problem. we check all the sensors n nothing wrong with it and end up is the intake pipe which is from air filter to the turbo pipe. The reason of the pipe is because of the heat make the pipe get softer n when u the pipe will b squire. Im not sure if is the same problem i had in customer's car.

Just bring it to the mechanic near the JB HIFI area. i already lost his phone number and forget what's the workshop call.

Good luck

Thanks halo,

Yeah thanks to alot of people who have given me some great opinions guys..... thankyou alot.

I think im gonna start by tracing these wires in the steering column and make sure there all connected up and not cut / faulty. I have no resivor in my 32 at the back so im guessing my hicas fluid is from the PS resivor which is full.

As for the idle im going to first clean the AAC valve and reset the base idle etc, change fuel filter and then if its still the same, take the coils out and check them thoroughly and maybe also cover them in industrial grade silicon just incase there starting to arc out.

I think the connectors for the plugs that connect to the coil packs are rooted as the little plastic insides have crumbled up? has that happened to anyone else yet?

Do i just hunt for a 2nd hand set of leads/wires with the connectors on? or can u buy those plastic bits new from nissan?

Also picking up a 2nd hand speedo as mine has split the plastic housing at the back and causes the speedometer to jerk about sometimes and plus the odometer has stopped working :S

Thanks guys for all the advice and help.....

Its great to know i can always ask the SAU family for some help

Cheers BOOSTA (pete)

try getting your injectors cleaned and see if it makes any difference, my r32 was doing the same thing - drives fine idles shit, when i got the injectors cleaned it fixed it. could also be the coolant temp sensor, the car thinks its cold all the time so its always running rich, might be worth changing, theyre pretty cheap.

Hey Guys,

Thanks so much to all who have replied, i have quite a good list of things to start checking over and one by one will knock them off the list.

I dont know what i'd of done if it wasnt for the help from SAU, Does anyone know a good way to check out cooler piping to see if its leaking air anywhere? Because my standard bov is bloody loud, sounds like a turbosmart atmo vent one even tho its plumbed back ?....

THANKYOU !!!

My List to check......

1. AAC valve and assembly (including clean out and idle reset)

2. Connect Wires in steering column and check over. (hicas checkover)

3. Replace Fuel Filter and check out old one.

4. Check over Coil Packs and also cover in industrial silicone

5. Check and possibly replace coolant temp sensor.

6. Check AFM and Oxy Sensor for correct readings.

7. Check Injectors and clean if needed.

8. Check all intercooler piping for possible air leak... as i think thats where the backfire problem is occuring !!!!

I put money on it that it is your ECU.

There is a series of actions you can perform to reset your ECU to factory settings. Do a search you should be able to find it.

If not let me know as I can find out.

if u wanna reset it, just unhook your battery and pump the brake pedal a few times.

i suggest taking the car to a workshop, they will find the problem alot quicker and easier than you will. charlies at wooloongabba know skylines very well, they deal with alot of them. im sure they will sort your problem out very quickly.

on the bov issue, u might find its stuck shut (if they can do that) the noise you are probably hearing is the flutter noise the air makes as it comes back out the compressor wheel of the turbo. try sourcing a new stock bov, it will most probably fix that.

      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

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
