Idling Problem with R32 GTS-t

[MM2death]

I replied to the R33 idling problem thread but to no avail. So i'll make a new topic.

After driving around for like half an hour and then park it, when starting up again the car will idle really low (from like 800 (normal) down to when it sometimes stalls). But after say 5 minutes it's all good again. Any ideas people?

Thanks

What would over-oiling your air pod do to the AFM and how the car runs? Any ideas? Just trying to eliminate some things.

Thanks

have tried cleaning your AFM and changed spark plugs.

[MM2death]

aight...i'll clean the afm. it has new plugs.

could be a sick fuel pump or dirty (filthy) fuel filter

got the same problems. Changed AFM, changed fuel pump, changed plugs, changed oil filters. ANyone here has any other ideas? We should make this a sticky, it's quite a common problems.

Skylines and idling problems go hand in hand.

Someone asked the same question in another thread, someone else suggested that it was the earth wire coming from the fuel pump. He said it needed to be earthed to a new area near the rear of the car. This way the fuel pump will operate at 100%. all the time. check the thread out, its in the 'performance' part.

When some dicks replaced the timing belt on my car (under warranty) he had it 1 tooth out on the exhaust cam.

This made it chew the fuel and idle weirdly. It would move up and down from 800 - 1200 rpm.

Once you turned the Air-con, it nearly stalled.

I don't think this is your problem, but you could always check it out.

Check the AAC valve, and clean it. Its the little valve located at the back of the plenum chamber (inlet manifold). Its what controls the air bleed at idle. Works like a screw moving a needle valve. If the screw or needle gets sticky, it lurches rather than run smoothly.

Where can i find the fuel filter? Is it the big metallic cannister thing below the intake plenum thats fairly visible and has a big clip to hold it to the chasis? Is it the one with the tube that goes in the bottom, and the tube that comes out the top and towards the fuel rail, or is it further back near the fuel tank, e.g. under the car? I should check mine i guess, although my problem is not on idle, but more under foot to the floor condition.

Just that on previous cars they've been much smaller.

yea i checked the aac valve and it was ok. but yeah i'm getting a 550hp fuel pump for my line in the next couple of weeks, so i hope that solves my problem.

thanks

You checked the AAC valve, or you cleaned the AAc valve? Every time I get this problem, carby cleaner in the AAC valve then put it back on, perfect!

Make sure you dont rip the gasket. Or it'll be going on metal to metal like mine is. I am sooo lazy!

[MM2death]

No i didn't clean it....it seemed to adjust normal though. but i will take your advice and give it a clean.

Thanks,

Scott
