Forgot to mention -
The shop that fixed the 'high idle' issue said he had to repair several Vacuum lines.
Before I took the car to the shop I removed the air filters and their covers.

When I got the car back from the shop I installed the air filter system.
Afterwards I started the car and the high idle issue returned so I removed the air cleaner system and inspected all of the vacuum lines I could see and no difference so after spending $600 to fix this issue, it's back

I wonder which vacuum lines he's talking about?
