been trying to figure out why my idle is so bad. think its my o2's but decided to check my tps voltage. i found that it was at .92 volts. tried 3 times to get the voltage to .98 but every time i tightened the bolts it moved and would go above 1v. when i loosened the bolts and tried to get the voltage down it wouldnt go. i pulled the tps sensor off the tb and it was reading 1.05v wtf? then it slowly goes up to 1.08 and stops and thats with the tps not connected to the tb. tried putting it back on the tb and that didnt work. tired putting a screw driver into the tps to see if i can push the sensor and get a lower voltage and that didnt work. is my tps broken? also, my wot reading is about 6.5v thought it was supposed to be 5v. how much is a new tps sensor and do local shops carry them or only Ford?
