hey, i am back again, i hope with the last my problem..
TPS becomes like crazy, most often when engine hot. engine wants to stall, rpm jumping sharply, if accelerating slowly, acceleration randomly halts etc..
connected FiatECUScan, parameter:
Throttle valve position (relative) - jumping from 0 to xx randomly. (engine starts to dance at idle), and:
Gas Pedal Position - changing from IDLE to Not IDLE (as i understand - it depends on Throttle valve position numbers).
so.. Faulty TPS?
i changed it a few months ago. bought some cheaper one.
everything was fine.. but it started to dance again!
do they really break so often..
when disasembled i checked it with multimeter, it shows smooth resistance changing when i rotate it. seems ok.. maybe becomes cooler while i get it..
was checking the wiring, but it has nothing with ground or signal dance..
ordered again.. this time Bosch.
(i thought, TPS start to dance, if throttle cable sometimes has not perfectly landed to zero position, ECU adapts new higher position as idle default and it start to confuse himselft, but maybe not..)
also.. maybe it becomes too hot? it is connected directly on throttle body.. there is no thermo gasket..
