Hi All,

Have a series 1 r33 GTST, recently had a second hand engine fitted all running well. Problem i have is witht the previous engine i started to experience an intermittent problem i.e on occasions when you started the car it ran like it wasnt firing on a cylinder, sometimes a simple restart would rectify and all would run smooth sometimes it just wouldnt run smooth for the whole day. Anyway that engine is gone and had new engine in for almost 8 months now never had a problem, in the last week or so it appears to be doing the same thing again start up she sounds like it has dropped a cylinder but this time i just restart and problem goes away, am worried problem will get progressively worse till its same as before.

Anyone have an idea as to what is causing this

did your mechanics tell you why you needed to replace the engine....and did they tell you what the problem was...if they did then obiviously its not the motor but could be the ecu, afm, sensors a lot of things timming for example....so just take it to an import specialist and they should be able to tell you whats going on

So many things could be causing it...main culprits are usually the coilpacks...ignitor...coilpack loom...then there are other possible causes like the CAS and so on...when the other engine went in...d you re-use any bits off the old engine?

other engine was replaced due to a so called "TUNING SHOP" in brisbane blowing my turbo and destroying number 2 cylinder after 16 runs on a dyno.

parts used from old engine were all harnesses and coil packs

you can get them from Nissan or opt for a second hand part but it could also be shagged. if u know anyone with the same model car try swaping the ignitor then the coils and see if the problem is still there (then again u said this doesnt always happen)

best of luck mate,

Have swapped around coil packs while it had old engine in always remained missing on number 4 cylinder tried another ignitor same probs sounding like it is most likely the harness.

Anyone know where you can get a new harness or is it possible to repair the old one?

Well...it might not be the case for you but it certainly was for me...after spending money on new coilpacks and a used ignitor i would still have that problem...then one day while it was happening i decided to unplug each coil one by one and found the dodgy connector on my loom...

      Automatic Power Button Light Flashing

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.

      Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
