Water thermowax not getting any water to make it expand hence keeping the throttle plates open more than normal.

Look into the throttle plate area and see if both primary and secondary throttle plates are closed all the way.

We won't mention a over tensioned throttle cable/cruise cable.

You didn't search good enough.
It has been covered countless times before.
I highly doubt it has anything to do with the AFM?
Why do you suspect the AFM in the first place?
Did someone tell you to replace it?

nope, just i had turbo part here and i had everything, manifold, afm, fuel rails, the only thing i have n/a is injectors and 3 inch intake, and i put everything together and ajusted the TB screw on the car doesnt wanna idle under 2500. i dont think i did a shitty half fast job because i carefully put it together and i cant find any intake leaks, that why my suspition if the AFM been a turbo one could cause the problem.

sorry to bother but i need some help that all

what TB screw did you adjust? the idle speed? or the throttle stop?

Are the throttle plates all the way shut or not. On a fully warmed up engine.
