Looks like a MAF issue? It only happens on the engine is not cold, probably after dinner or got off for a while, start car, air con on and run, rev may drop to off. But then turn it back on, run first maybe 5 second, in order to turn on the air con, it is fine. Any idea? Thanks.

 

Not a MAF. Clean your throttle body with some started fluid first. It is free and a dirty throttle body can cause wierd things to happen. If that doesn't help I would check for vacuum leaks.

 

I am experiencing the same issue. Let me know what works for you. I am going to try TB cleaning first but also thinking of replacing the alternator. No engine codes either

 

any of you have a LWFW?

 

disconnect the positive from the battery for a few minutes then see if the car turns over...

 

I have stock flywheel with stg2 clutch. What does disconnecting the battery point to? I'll try this out tomorrow.

 

resets itself... clears soft codes etc... check underneath and see if the black colors o2s are closer to turbos... and see if they are connected on top......

 

No, I don't have LWFW neither....

 

Besides, I have the secondary air injection code (P0492), but I believe they are not the same case right?

 

It shouldn't be because the SAI pump shouldn't be running on warm start IIRC.

 

Any updates?

 

Nope from me...my workshop not willing to clean the maf for me, too risky.

 

Here is a video of exactly what happens to my car. Warm start after about leaving it for 1 hour (dinner). Took this video just a few hours ago. Every shop I have spoke to says this is hard to pinpoint and can be many things...expect to pay 5-10 hrs for trouble shooting.

So I am think I mine as use that money to replace my alternator and get the TB cleaned. Looking at the video it looks like my voltage reading is low which causes the car to stall?

Exactly the same as me, but mine not going off so soon, and not too often.
