Alright, i am having a few issues with my car and i've tried a few things but still haven't fixed it.

Stats:

rb20det power silvia. rb25 tubo, stock exhaust, hks mushroom pod, malpassi rising rate fuel reg, vl turbo fuel pump, injectors flushed and flow tested spot on last week. EL falcon o2 sensor mated to skyline plug, rb20det wastegate stock boost (around 8psi), afm cleaned regularly.

Problem: when my car is at idle it misses and the revs drop a little. This is intermittent (spelling?). Also, when on the gas peddle and if i back off, then accelerate again sometimes there is a big miss and it's a little hard to start in the morning. Overall, my car doesn't perform as good as what i think it should. Uses about 350 klms to a tank.:headspin:

This problem has been around for a while so i got the injectors flushed and flow tested. They were spot on, i recently put a fuel reg in and set it at 40psi, now the car is a bit easier to start but is still a pain. NB, i didn't remove the stock fuel reg.

Does anybody have any suggestions for this at all?? It's driving me crazy. :blast: Im going to remove the coil packs and give them a clean shortly.

Any ideas, comments and suggestions are greatly appreciated

Thanks :)

Jayson

cleaned the aac valve yesterday. That's the thing mounted on the back of the manifold right with the cylinder like contraption bolted onto it?

Fuel pump was new about 4 months ago when i did the conversion. Plug gap is about 0.8 i think. bcp6res are the plugs im running im pretty sure. I'll double check the bov for leaks i think.

Thanks people

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
