Hello,
I have tried cleaning my throttle body and my EGR valve. I have a 98 STS, and I swear there is no stopping to this idle problem. Should I replaced the crank position sensor? Would this help? What would help. Please give me any factors of a rough idle that I can check out and try to fix. Which are the pieces that would do this.

Thanks!

There is no codes at all. It runs rough when I drive and it idles rough. I cant figur it out.
