Hey guys, having a problem on my 97 s2 r33, when starting the car cold it will start up fine but cannot be driven for 3 - 5 minutes as when the throttle is pushed the engine sputters badly, can anyone help or had similar issues?

So far I have -

Cleaned the AAC valve

Cleaned the AFM

Cleaned the throttle body

Checked for vaccumm leaks

Tried adjusting the idle screw

Current engine mods on the car

Haltech platinum ecu

750cc injectors

Walboro 250

Top feed rail

Gt3076r

Spitfire coilpacks

Z33 AFM

Any help massively appreciated as it's slowly getting more and more annoying

See these threads all the time. Most are usually tune related.  But more information is needed to work your problem out.

How long has it been happening? Have you done anything recently that has triggered it idle shit?

Bought the car around 2 months ago and it started fine but idle was high so I cleaned the afm, throttle body and idle valve etc and the idle was better but then I think the cold start problems were amplified, could the car have been tuned whilst the afm and stuff were dirty thus causing it to run differently now?

      RB25DE NEO with Haltech ECU

      @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.

      I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.

      Duncan's V37.......race car?

      Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
