Welcome back.
Okay, P0507 - Idle speed higher than expected.
First remove the negative battery connection for about five minutes, this should clear the idle memory. Reconnect.
Start the engine and rev it to 1,500 rpm, then back to idle (500) then back to 1,500 and back to idle.
If you have the code return and the idle speed is high then verify that there are no vacuum leaks as they can also set this code.
