That is what I have done.. still the same.

All sensors apart from the tps and iscv is new. Just fitted after a head rebuild.
The iscv is not sticking when pushing it carefull with at screwdriver (holding it in my hand).. the piston can move very easy. But the condisitions inside the throttlebody may be different afcause.
The tps work according to my multimeter.. 42-48ohm closed to 630 ohm fully open, with NO glitches

But... CAN the ISCV cause idle in the range of 12-1500 r/min???
