I've got my car remodifed after compliance with my head back on and the damn thing won't idle. The car was only run a couple of times before it was demodified so i'm not totally sure but i'm pretty certain it didn't have these issues before.

The car, if its cold, will start first turn of the key and idle fine. Once the car heats up and the AC or head lights are turned on the car stalls. If you try to drive the car and brake and revs die down slowly it stalls. After it stalls you need to pump the accelerator to get it to start (sounds like a carby car) then it won't idle. It seems if its starving of fuel, but where and how?

Also since the car has issues at the moment i haven't been game to run any more than 0.5 bar boost, however the exhaust temp gets up around 900 degrees on this boost, where as on 1.4 bar previously (before de modified) it never got anywhere near that - yet again under fueling.

The Car has things like a greddy plenum, HKS Fcon V pro (AFMless) ECU, Tomei 270 degree cams, HKS GT2835 Pro S turbo etc.

Should i be able to run my AC and my head lights and still get the car to idle with these cams?

To me it seems like its starving of fuel but i have considered other issues like the TPS being out as we swapped the Throttle cables over for the greddy plenum, would this make a difference?

Thanks in advanced.

I'm pretty sure the TPS has to be within a set tolerence of 0 (e.g. 0.5%) before the AAC valve will attempt to control idle. So, yeah it does sound like it isn't set corectly. It idles fine when cold because the air regulator/cold air bypass valve is fully open.

ok, car seems to run a little better now, got rid of the PCV and blocked it. TPS is spot on!! Fuel pump is hard wired, Hopefully a decent tune and a power fc will sort out the remainder of the issue.

    • All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible  
    • Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.
    • They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox) They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox)

    • Yeah, hard to find and a pain in the ass to change with the transverse engine. I’ve worked on a GTiR before and it’s not a job I’d ever want to do again. theres a company in South Africa that makes RS3 gearbox adaptors for the AWD SR20 including gearbox mounts, so I could modernise it and go a dual clutch with paddles. For now tho, it ticks all the boxes. Super cheap, can throw the kids and their junk in the back, and SR20 that I can turbo cheaply, a CVT that’s not a dog’s breakfast like the V35, and has 80% interchangeable parts with stuff I can source from the wreckers cheaply…. But it’s still unique. I love the wagon back of the Autech version. It’s cheap enough that I can buy another stock manual FWD Primera with SR20VE, swap the gearbox to the N15 pulsar short gear ratio box, swap out the brakes to the R32 ones I pulled off my 32, register it on club plates and take it racing. $1300 shipping from NZ. Heaps of parts and aftermarket builders for transverse SR20’s in NZ.
