Hey guys, I recently bought an Evo 8 with a little over 80k on it. I just now noticed when starting up the car seems to be idling a lot higher than normal 1500-1700 rpms when initially starting up. After awhile it will go back to normal. Is that normal? Also when doing this the entire car is shaking a lot more than that I remember when initially getting it.

 

Sounds normal for initial cold starts.

Maybe a popped off vaccum line or boost leak.
