What causes super high idles like this?
 

Sometimes I'll clutch in to stop at an intersection and my revs will sit right at 2k for like 4 or 5 seconds. It doesn't seem serous, but I'd like to know what can cause it...

same here, it's stuck at like 3k for me before...i'd have to tap the gas to get it to come back down, but like you said, sometimes it'll come back down automatically...either way i'm right there w/ya, i'd like to know what causes it too!

pretty much normal. mine does it as well and has as far back as i can remember. Wheather afects it and humidity and all that stuff. mine does it at 2k as well for about 3-4 seconds then comes back down to idle. mostly after highway driving.

Haha glad I'm not the only one. I'm not gonna lie at first I was like, "WTF is wrong with my throttle?!!" lol

yeah mine does that as well
