Sometimes when idling non cold air comes out of vents with A/C on. Also, during quick accelerations or up larger hills, the air flow from vents dramatically reduced.
Do you

I suspect your system is just low on charge which could be caused by a leak. so we need to check out these guides on how to figure this out.

We can start with what the pressures are to confirm this but I suspect we are going to need to put some Freon in it just to bring it up to proper charge.

Let me know what questions you have. Thanks
