Warm idle issue - Help

Hey all, Need a bit of help. 

Been having this issue for a while, It starts having idle issues when the car is warm, usually after about 15-20 minutes, I have got videos of what it sounds like when cold idle and when the issue starts to happen. As well as NDSI logs of as the car heats up and the when the issue happens. It was at protek automotive for about a month and they didnt find anything. 

 

I replaced the coil packs with new ones it kept happening, then i replaced the spark plugs with new BCPR6E-1, then also resoldered the AFM solder joints. 

Any insight would be more than welcome. 

 

What the exhaust sounds like cold. 

Issue as it starts to happen and get warm.

 

Issue as it gets worse.

 

What it sounds like from the drive side fender. 

 

 

I really hope someone can find what the issue is, I'm getting pretty sick of this not working.

Thank you all so very much.

Hi yes, sorry forgot to post the fix. The cas on mine went bad. The post that spins was really hard to spin. Got a replacement and fixed all the issues. Later took the broken one apart and lubed up the bearings and that fixed it. Put the ex-broken one back in the car and it's been running fine since. 

After it did what was in the video it would just stall and sometimes start again, some times not.

Cheers. Will have to look into that then. As I’ve pretty much done all the same swap outs you had done. Plugs, coils, air filter replaced a few cracked vacuum hoses all to no avail. Was just about ready to pull the maf apart to look at solder joints but might check the cas first

Cheers mate. 
 

recently bought a consult and plugged that in. Came up with 15 faults for maf sensor and one for knock sensors but says 0 starts in brackets??? so got me a second hand maf and I cleaned out the throttle body while I had the piping apart. That was filthy. All seems to be going well now. I’m going to hunt down the knock sensors to see if they are properly connected and the wiring is in good condition as from what I’ve read the sensors are pretty bullet proof. And I’m wondering if the 0starts means it isn’t picking them up but not sure.

I wouldn't think that the knock sensor would be causing a warm idle issue. Maf would. 

 

Mine comes up with 0 starts after resetting the ECU. If you turn the car all. Leave it for 5 minutes start it again does it come up with 1 start?

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
