Hey guys,

My skyline (GTs-t) has done this since I got it. When you start it up for the first time in the morning it sorta struggles to idle on its own, if you give it a rev, the stepper motor kicks in and its fine from there. Then when your driving, under medium throttle it surges a fair bit. If you floor it its fine, but under some throttle pressure it stumbles and surges. Once its warm, its fine.

The fuel pump isn't audible from inside the car so I'm guessing its the stocker so that could be the issue but I'd like some ideas to make sure.

thanks fellas!

the most common culprit for this sort of thing with R32's is coil packs. there's a lot of thread regard these stalling/start up issue so search around...

its stock ECU, only exhaust and filter......

yeah I replaced one of the coil packs soon after it landed cause it was a dud..... Kinda a lucky dip with second hand coils though. It runs fine, just after start up its dodgy....

anyone know how much new coilpacks are? genuine or splitfire?

anyone think it could be something else?

mine does the same thing even if i let it idle for a bit ever since i got it

as far as i know stock ecu wheres it located soi can have a look see?? just got a pod and a bigger exhaust that came with it n the boost been played with before i got it but dunno wat its runnin at now

Mine has done this since day 1 of driving it (been on the road for over 2 yrs now). Once the temp guage gets to half way, shes fine, just warm it up if it pisses you off, if not don't thrash it till its warm. I get in mine cold, drive it straight away, 2-3 mins max, its warmed up. You can feel it hit that certain point once the temp guage is halfway, it 'clears up' and feels normal. Done it since I first got it on the road. Quite common apparently.

Don't forget, these cars are getting old now, mines a late '93, 12 yrs old now!

It's most likely to be the cold start programme built into the standard RB20 ECU. My car also has these characteristics, and its 23 years old!

FYI, the ECU in an R32 is located in the passengers side kick panel.

hi, check the plugs for the temp, one for the gauge and one for the computer, put the plugs on two or three times just to make sure the contacts are good, the computer prob thinks the temp is diff to what it really is. These sensors/plugs are pretty old by now and more than likely wont be operating 100%. this is where i would start first. The plugs are located by thermostat/ top radiator hose on block.

try starting it without using accelearator, if it wont start then open bonnet and wiggle plugs/ remove & replace plugs and try starting again.

My r33 used to run rough under load, around 5000rpm, and it ended up being hair line cracks in the front of the coil packs. after wrapping them in electrical tape, i havent had any problems with them. This is a common problem with r33's

sorry i should have worded it better

its not a reason to accept that its not doing what it should. eg i have friends and go well the my car overheats (or anything really) but it doesnt matter coz its old. my thinking is ok it overheats so replace the thermo fan thats not working - dont just use the 'its old' as an excuse to not do anything.

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
    • Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
