TPS light (homademade) only lights on acceleration?
Hey folks. So, I might just be retarted, but I am having a slight problem with a home-made TPS adjustment tool.
I built it just the way all the threads here say to: two 12V LED's and some spade terminals.
When plugged in, trying to set the TPS, only 1 light will light up when the throttle is opened rapidly, and then goes dark with engine deceleration.
No amount of adjustment will get it to leave either of the LED's illuminated at idle.
Has anyone encountered this issue before?
A new TPS is on the way... let's hope that'll magically make it behave correctly.

you adjust it with the engine fully warm and OFF, but with the key to on.
sometimes it takes a while to get both the lights to come on. then slowly turn until only one light is on

When setting the TPS, if I open and close the throttle and let it come to a rest, I get one reading. Putting a little bit of force in the closing direction changes the reading a fair bit; going by resistance measurement across the "narrow range" pin, it drops from 1kOhm to 0.883 kOhm.
Do I need to clean out my throttle body? Or is that offset effect to be expected?
