I have noticed before the TPS readout on my Microtech sometimes starts to wonder randomly? Is this common with the 20B Sensors? I can set it up fine and then when it gets hot it can change and I have also noticed if you sit with the ignition on for a long period but engine of it will eventually start to wonder all over the place. I guess it is a variable resistor so heat and voltage change will effect them but I don't know how sensitive they usually are. Do I just adjust it back a bit to overcome the wonder with heat and then under normal running voltage fluctuation should be minimal? If it wonders it messes up my decel kicking in and stuff so would like to try and out it out if I can!
