my idele used to be at 1k but now it idles at 1500 to 2k rpm and i think its my throttle cable but i moved it and it still does it

 

Vacuum leak or stucked EACV.
1. take the intake pipe off and block with your thumb the hole to the left side of the throttle body ( inside the TB ) If there are two holes block both.
If the idle drops, then the EACV is clogged. You can fix it temporarily by removing it and cleaning it with carb cleaner.
2. If #1 didn't help. you have a vacuum leak probably at the brake booster.
Good luck.

 

is there a write up to do that??
