well i bought it at a toyota dealership and it came with a warranty so for free they replaced all of the spark plugs, throttle plate, all of the the ignition coils and cleaned the throttle body, the best they could do. i am getting no codes and it runs great except for the annoying idle. i am almost 100% positive it is the throttle position sensor because i lubed the cable and everything else has been done also i checked for a leak in the vaccum lines and i cannot find any, i even replaced all of the grommets. i just need to know how much a TPS usually costs and how to replace it, i hear it isnt hard but i am not an expert at auto repair, ive replaced o2 sensors before but is this alot harder? i mean i am mecanically compident but i need help! THANKS ALOT! ANYONE!
