so my issue is that after my car has been warmed up, the idle stays around ~2000rpm. however, if i turn it off and start it back up in about 10 minutes, it idles where it should (1400) with no problems. however, after driving it around, idle increases to about 1600-1700 instead of 1400. i have a half-bridge 13brew single turbo with all the block off plates, running a pfc with datalogit. TPS and boost sensor are fine, checked voltage and they're within spec. any suggestions? thanks in advance

yeah. should i completely remove it or how do i fully disable it? as far as I can see, they aren't connected to anything that will affect the idle..

don't run the fast idle system without the coolant hose or your throttle plates will stick open when the engine is warmed up. you will need to remove the thermowax from the TB, or put the coolant hose back on so the idle drops down once the engine is warmed up.

Or just screw in the adjusting screw under the wax rod so that it disengages even when cold.
If it will not screw in far enought to disengage, then stick a spacer with a hole in it between the parts to open it more. A small nut will work.
