I extracted some error codes because of a high idle(2.5K). When I took off my throttle body, the paper gaskit ripped and like a moron I re-used it. But anyhow, I'm getting the new gaskit monday, but I cheked the error codes to see if it was something else. I got these codes: 12-Throttle Sensor(full range)
18- Throttle sensor(narrow range) What does that mean?

 

did you forget to plug in the tps?

I'm so dumb. I forgot to plug in the TPS. Now, my idle is really high, it wants to jump to 3k rpms, but then the computer kicks in and brings the idle up and down between 2k and 2.5k. I'm almost certian it's the gasket for the throttle body(which is in 3 pieces) Could it be something else though?
