Idloinig pretty high?

Sometimes my truck will be idling higher than 1K, more like 1.5K

This bad?

 

That happens to mine in the cold.

 

Ya in cold weather I think they are built to idle higher. I've had mine idle as high as 1800RPM off of a cold start. It idles lower after it warms up I find.

 

also if you have it in park it idles a lil bit higher, at least thats my case

mine does this too but its hot outside....i dont understand!!! it didnt do this before!!!! before u couldnt tell it was running n now its loud....wtf happened? what do i need to do? take it to the dealer?

 

My '98 did this but I had the CEL come on.

Figured out it was the throttle position sensor.

Replaced it and it worked just fine.

I normally idle (warmed up) around 750-800 rpms... when it was all screwy it was idling at around 1500-1600 rpms. Very noticeable difference.
