Ok i did use the search and the main fix i found was replacing the TPS. I replaced it and the car still continues to idle either too high or too low. When its cold it will idle about 400 to 900 and just goes back and forth. And when it warms up and and i floor it will idle about 1200 to 2000 rpms.

What else could i check for this problem?

 

A scan tool to monitor the computer data would help in determining what is wrong. It could be lots of different things.
