I am having an idle problem. When i start my car it idkls at 1500-2000 rpm, no codes or anything. Recently replaced the tps, since it was throwing a tps code. Anyone have a clue what it could be? Sometimes when i turn the car off and back on it idles at a grand. Recent tune up,

 

I think there is a paragraph in the Haynes manual that talks about how to calibrate the TPS but I don't have my manual right now.
