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.

Does not seem to be the O2 sensor on the exhaust, I disconnected it completely and it did the exact same thing.

Did you ever find the cause. I have a similar issue with my 34 20de neo. Did it also randomly stall at idle

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
