Y bracket surrounds

What's the easiest way to check the AAC, FICD, air reg ect back of the throttle?
The Y bracket still in, but when I'm first trying the ALS function (I know, it's dangerous ) lost my 950rpm idle. It increased to 1600 rpm whit correct AFR, but when I changed back the factory ECU, idle drops to 1000, but 20-22 AFR (whit 560 injectors!!!).
So I think is there some leaking, or some of these air regulators freaked out.
I'd like to check them, whitout remove the engine

whats als function?

there is no easy way of checking it if the Y bracket is still there, you would be best off removing it as the iacc lies right underneath it.

could be an air leak though or possibly other sensors breaking down

Haltech ALS function.

What meens "other sensor breaking down"?

ah right
tbh im not sure then as don't know anything about haltech or als function on it

if alls working ok with stock ecu then it could be something to do with the settings on the haltech itself

Haltech: 1600 rpm, 14.4 AFR (ALS off)
Stock: 1000 rpm, 22 AFR.

So I think, engine receive more air then needed, and the two ecu compensate it differently.

yeah possibly air leak somewhere
what are vacuum readings like on idle?

I'll check it later.
Exhaust is loud enought to hate me the neigbors.

Found the faulty calibration plugs:

Ooohhhh, and that's not because the ALS!

I think, the setting of the new ecu was faulty.
At cranking, sometimes stop the cranking immediatly. Maybe the ignition setting was wrong, and the engine start to rotate backward only for one tact. Thats why some pressured air came back at opened intake valves, but closed throttle.

Should they be either blanked or looped not left open ...

Fortunately I found them, I put them back.

Glad to hear it was a simple fix  

The idle not checked yet

Is it just the photo or are you a screw missinng from throttle body under accelerator cable. Could be photo as there low down

Yes, my mobile cam hasn't a good dinamic range.

No problem thought it might just be the picture as long as its in good luck with sorting it
