Hey guys after my car has been sitting for a couple of months and not driving on any roads only idling around a paint shop and car park, I decided to drive my car home to do some other work to it. When I started the car up the idle sounded alittle different. It didn't worry me until I took off on the road and it missed and stalled and wouldn't start inless foot is flat.Ok so the car will start first very well when cold and will idle well for about a minute after that it misses chases idle and sounds dreadfull.

I've done the following mods before the car about 18 months ago. Car was running beautifully.

Wolf Ecu

R34highflow

plasmaman intercooler kit

Dual stage boost

Full 3 inch

Splitfire coilpacks packs

Borsh fuel pump.

3inich metal intake.

no bov.

The car was running 16psi and never missed or carried on until now. Anybody out there ever had this problem.Or know what it could be? Thanx guys

Me too I've had a few skylines. I checked the spark and my plugs were very dirty after only a week of moving the car around the garage. I think my coils are stuffed but wat could be causing the ignitior to kill my splitfire coilpacks. Evilness!

Fresh. 3 day's old! I'm goin to put a new fuel filter in the 33 today. If the problem is still there I'm going to clean the AAC valve and put more new plugs in.

If the misfire is still there after all that. Gap the plugs down to .8 if there not already .8

Its probably the Borsh fuel pump choking on the gravy :yes:

Is it Bosch or Borscht cos it can have a huge effect.

But seriously think about checking your fuel pressure and see if your pump is still OK. Sounds a bit like fuel starvation to me.

Over a yr later I'm back on . I had 1 coil pack go and a faulty injector . Car runs like a bullet train now on boost . Now the only probly is if can take a bit to start ( pump accelerator ) and somtimes back fire on start up .  I've done a compression test . All good . So yeah bit of a timing problem .

    • AFM looks to be a z32 The injectors maybe old Nismo 555cc The turbo tag when looked up seems to be a gt2871 , imagine it would have the bigger rear housing .82 all look like the mid 00's mods when he started building it up. Vac hose seems right but would need to see a diagram. Great work going up there and sorting it out, be a good club car for someone wanting a good reliable rig.  I know I would like to have it but no space and too many other race cars at the moment.
    • Heys guys I got a r32 gtst speedo is out by 10kph seems the faster I go the more it be out  just seeing if anyone else had to problem and knows how to fix it 
    • I can't agree. If we hadn't all been brought up with the noise caused by the inefficiency of an ICE, no-one would actually ask for all that. An EV is like any other car, it just goes better. 
    • 2 more things I have to work out Easy one first...can anyone describe how to pull the fuel pump and sender from a 33? I can feel there is some sort of mount and clips but don't have a manual and don't know the trick......if not I'll spend some quality time in the boot witha lighter tomorrow. Second question is harder.  He had changed the upper plenum to a plazmaman but clearly got to a point with the vacuum hoses where he said "f**k it, I'm going inside for a beer" and never came back to that job because it was a mess. Am I right to think that I need: 1. Pre throttle (16mm nipple on inlet) to AAC's main 20mm fitting as the main pre throttle feed 2. ACC has a second 13m outlet joined to that 20mm fitting which I think is the pre throttle air supply for the cold start valve? 3. Cold start valve's outlet fitting then goes to Plenum (to bypass throttle?) There is some adapter on the back of the ACC with 2 fittings (13mm and 10mm), do I run the 10mm through a 1 way valve to the Brake Booster (4) and the 13mm back to a 13mm nipple on the Plenum as the Idle control (5)? 6. Run a 6mm vacuum line from the Turbosmart BOV to the Plenum? 7. Run a 5mm vacuum line from the Fuel Pressure Reg to the Plenum? 8. Run a 5mm vacuum line from the Turbosmart Boost controller to the Plenum? (Wastegate already has a pre turbo pressure source running to the solenoid then the wastegate on the other side of the bay)  Any help appreciated, the GTR is quite different setup and while the Stagea also has FFP it is different again. (And no Dose, I'm not pissing it all off and putting a ethrottle on it....)
    • OK, onto some questions to try and speed up the process a little. Does anyone know what core this Garret is? I know it is a high flowed standard turbo but nothing else about it. Tag says OK 0169J - 446179-5032 Same question for the injectors, I don't know what they flow and ideally can work it out before it hits the dyno, they are a mustard yellow side feed
