Hi guys, I have a really weird problem with my TPS sensor... I have stock 99 si and it was running perfect. Just the other day, I was sitting in the car and it was idling for a good 15 mins... THen suddenly, the cel went on and idle went up really high... Ok checked... its cel 7 thats tps sensor. I went home changed to new tps... didnt work... idle really high... roughly 1100 - 1200 rpm. After driving it for a while cel goes on.

Today I used a multimeter and tested the volt. I tap in the middle wire (Red wire) and it shows ~4.9 - 4.8 v Close Throttle... then I open throttle to full open it the volt didnt change!!??? Ok, so I thought my new used sensor is no good... so i got ANOTHER one, same thing.... it's still showing voltage CT or WOT . Please help me? Whats going on!?? thanks
