when i start my truck warm or cold it idles really high like some times 1500 rpm or higher sometimes it lowers down to normal, sometimes it dosent. Other times it starts up and idles fine. The idle also sticks high while driving and i can notice it when i come to a stop. I was told it could be the throttle position sensor. This is a new truck to I always owned pre smog trucks. please help, its getting annoying to deal with. thanks

 

Check for codes even if there is no check engine light.

 

could be TPS or IAC...clean them both...see what happens. good luck.

 

How do you clean the sensors?
