[High RPMs connected to knock sensors?]

Awesome! Thanks so much for your input! I've got the sensors ordered and the dealer I bought it from is going to put them in for me for free..so I'm gonna hope this fixes the issue before giving up on her! haha 

 

Thanks again tho, I really appreciate it!!

[High RPMs connected to knock sensors?]

I have a 2002 Highlander (V6, 4WD) and last week the check engine light came on. Went and got it tested and it threw the P0330 and p0325 codes for the knock sensors. Which I'm making plans to get replaced. 

Now this week, when driving on the highway the RPMs will occasionally be at 4thousand. When I stop and restart the car the problem seems to stop for that trip. Is this irregular RPMs potentially connected to the knock sensor codes I got? Or does this sound like another problem.....?

Also, would knock sensors be an ok part to pick up from the Pick-a-Part? They seem to be pretty expensive brand new and there are two in this vehicle...just looking for more economic options.
