S4 13BT Auto, Engine keeps Stalling
 

My auto FC keeps stalling and can't seem to hold steady rpm.
Anyone have any idea what the cause may be??
This vid is after a cold start, the only time it runs.
When it's put in Drive, it just stalls out.
Keeps missing quite a bit too. But I guess replacing the Plugs will fix this issue.
Can be kind of driven around if you use both pedals at the same time.
The car is running a microtech ECU of some sort.

The same time these problems started occuring all electrics have slowed down, e.g Windows take 2-3x longer to go up or down, Wipers slow down heaps.

All these problems occurred simultaneously one fine morning and No I hadn't fiddled around with random shit. The car has been untouched by myself in the six months I've owned it.

Would adjusting the TPS and cranking the idle to 2-3k help it temporarily?



The Pic include another possible issue. Looks like a gasket has blown and is leaking black stuff. Anyone can help with ID of gasket/seal.

Cheers for any help

i dont see any black stuff, so i cant tell where you are describing.

as for the stalling and all electrical slowing down. you should monitor your voltages to the car and ECU, that is where i would start.

The voltage output of the alternator should be close to 14 volts when the idle speed is close to 800 rpm or so. If the voltage is too low it could cause the car to behave wonky (that's a down under term isn't it?).

In the last pic those are all blanking plates where acv, twin turbo input/output, nipples have been deleted. These plates shouldn't leak anything as they are just there to keep air in the uim/lim.....if black stuff if coming out from these something is seriously 'wonky' with your engine hehe :d hehe
