Ok thanks now that i have changed the tps i unmounted the battery so it can reset it self.. Now when i start the car up the car is idling very high like reved up between the 3 n 4 rpm mark... Wat could cause this???

Go back and recheck the TPS. You must put it in off set to the holes and then turn it back. Check the write up again, it will show you.

I moved your thread into the Bonneville Mechanical & Maintenance section.

Second on what Dan said. I made the same mistake and wondered the same thing.

In fact, I've changed that sensor a lot and still make that mistake from time to time, so don't feel bad.

Yep! been there done that. You have to be sure to insert it in the throttle body then rotate it into position. That little spring needs have a little tension on it or it will make the engine rev well above idle.
