1HD-T idle drop when facing upwards-FIXED (1 Viewer)

[KiwiDingo]

I just try, it is not possible, not even close

So weird. People do this all the time with pump still installed.

i think its more likely 1hz without boost compensator pump cover..1hdt not possible, no way

I pulled the pump out and change both of those springs, nothing changed.. still drops idle upwards and dies when turning wheels with warm engine..what a hell this could be?

parts seem different from the original poster I've got an Early 03/1991 HDJ81

Does anyone have a source for these springs?

is K=0.25 vs K=0.28 the spring rate? 0.28 being the stronger spring???
