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.

    • There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)
    • What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
    • ...oops. forgot the TCU end...
    • No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here. 
    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
