V35 350GT Skyline - Engine missing and No power at high revs

Hi Guys,

I've got a 2003 V35 350 GT Skyline and I've been having an ongoing issue with engine missing and then no power at high revs. It only seems to be after I've been running the car for a while or at the end  of a trip home from work (about a 30 minute commute). I've taken my car to a mechanic a while back when I was getting a service, the missing happened at that stage while idle but it didnt seem to effect the power from the car. It had gotten a lot worse and took it back to the mechanic and they claimed it was an iginition coil.

They replaced it, drove it to work in the morning no problems. Then on the way home I when I first started driving, it wasnt too bad, maybe a rough idle at times. Towards the end of my trip I tried giving it a bit of power and it as soon as it went over 4k revs it just loses it's power.

I've gone to this same mechanic in Brisbane for years but I always seem to have issues where I have to come back to look at things so I may have to look at going to someone else. Does anyone know what this kind of issue sounds like?

Thanks in advance,

Jonno

I suggest you take it back to the mechanic and have him check whether

 1. There is any oil leak into the sparkplug chamber

2. Engine Compression for any leak, if there is then an engine rebuild is required which might cost thousands. In my case my mechanic is able to fix it with a few hundreds without having to rebuild and my car still performs well.

Is there any stutter with the rev during idle?

Sorry for the late reply! Haven't been able to get back on yet.

Yes it has a rough idle, but this is where it's weird. If it's cold there is usually no issue but give it about 10-15 mins of driving, when I pull up to a set of lights I get a very rough idle.But this is when the car is in drive, once I put it into neutral it stops happening, or significantly less then when in drive. Who is your mechanic? It would be great to get in contact with him.

I think there might be something wrong with the Camshaft/CrankShaft sensor as well and it is a factory-recall reported issue for our car model. My mechanic managed to narrow it down to which one specifically and my car has been running fine since then. 

He is based in Bankstown. I'll inbox you the full address if you are still interested

FYI, rough idle usually can be fixed by cleaning the Throttle Body and performing idle relearn procedure. Then after doing all that and the issue is still there then the Cam/Crank shaft sensors are next to be looked at. 

My mechanic and I went through the whole eliminating process to narrow down the root cause.

Hope that helps.

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
