Fast Idle Thermo Valve on your throttle body.

yep...pull off the plate on the side and screw the white plastic nut all the way down and use some loctite.

someone told me it might be my intake manifold that is dirty how true can that be

[Hybrid_Coupe]

i doubt it. it is your fast idle valve.

If it was your IACV, which is ON the intake manifold, but is not the intake manifold itself, it would also do it when the car is warmed up.

it does not it stops after it warms up and after that it perfect it goes down to almost zero and no shake or nothing vetc even kicks in at 6000rpms if thats right

i took off my filter tube and there is oily gunk along the wall of the manifold could that be it

thanks for the input

So then it's the Fast Idle Thermo Valve on the throttle body.
