Bump

I've checked and double checked all the vacuum hoses. I haven't checked the plugs yet for a few reasons: - I just popped in 6x new NGK Iridiums - I just cleaned and resealed the coil packs (Misfire under load was an issue) - and last i checked, the computer should be able to keep the motor running even if it was one cylender down. From what I can tell, the computer is either not getting what it should to kep the motor running, or there is a piece of hardware not doing what it shoud be to keep the motor running. QWK32, I tapped into and resealed the silicon elbow using a little trick I learned from working with large dia pnumatic hoses. It was ahellavalot easier than welding a tap onto the aluminium pipe.

The tune is set to default, as the PFC comes out the box, with the exception of the boost control setting disabled and the Z32 MAF sensor option enabled. The MAF sensor is fine. Both the hand controller and my multimeter confirmed this. The unit came off a working car. Timing? Possibly, but I didn't go anywhere near the timing. And to go out by that much???

I forgot to add she's also running very rich. I think that counts too.

All these parts are brand new, besides, the motor revs ok at high rpm when the drop in pressure would be at it's highest. I don't think it's a leak anywhere. I've heard this car run with a leak. Like I said the idle is pretty rough.

Why is that? Does it create a vortex within the pipe and just confuse the mass sensor?

I put in 20 litres of Mobil 8000 on Monday. The Power FC is set to use the VG30 (Z32) AFM. The breather hose would normally get plumbed back into the intake, but it's not needed, I'll slap on a mini filter later. And the AAC does get it's main feed from the silicon elbow. It too is plumbed into the intake on the stock setup.

Hey everybody! Hoping some ppl can throw me a few pointers. My car has been off the road for quite some time on account of me loosing my licence, so while it's wasn't going anywhere I thought i might as well do some well deserved modifications. Now I'm done and the car has trouble starting, it won't idle, it runs really rough, but if i squeeze the gas, she'll rev, but it almost sounds like she's running minus a cylender, then when I take my foot off the gas, blah, it dies. I've gone through some of the basics today, but I can't find out why it's running so rough. Can someone shoot me some pointers? This is the list of work I have done to the car while it was in my garage: - Stainless steel extractors - top mount turbo - external wastegate - dump pipe - electronic boost controller - FMIC - BOV - Apexi PFC (crushed the original ecu, can't even test it on stock ecu!) - Z32 AFM So that has taken me about 5 months on weekends and so on, now I've got to troubleshoot the fault. Any thing I may have installed or done improperly that could cause this? If I can't figure it out, I'll get a mechanic to look at it, but I figured I got this far on my own, I'd love to fix it on my own. (with SAU members help of coarse!) I have included a pic of the engine bay if it helps. -
