Thanks, I'll try clean them tomorrow.

I messaged Gongo, because he had a similar problem. Here is his thread:

Weak Start / Stall (youtube Video)

He stated "I don't recall exactly but first I cleaned up the throttle body assembly. I later on experienced a similar issue but it was the factory battery weak on its deathbed. It died on me after 1.5 years and i replaced it with an optima red-top."

Hope you solve the issue, and if you do, let me know.

Dnt take it to a dealership, they'll bull u and will try to charge u double. Best bet is a Z special shop around your location.

Original battery isn't maintenence free, so it might need water or replacing. One of the plastic rsoonators may be cracked or a hose clamp may be loose. Run the car, while running spray carb cleaner along the intake tracts. If the idle changes you found your leak.

Failing that, an exhaust leak anywhere near the primary O2s can cause these problems as can faulty mafs.

After that it might be failed throttle bodies, which allegedly is not uncommon for this motor.

You are under warranty on drive train for 50 k so taking it to the dealership isn't necessarily a bad idea after doing own troubleshooting.
