I know it will cost me about 145.00 BUT Do I need to have the car with me to get the key?

I lost the ONLY key and it's parked at my job...

I want to recharge my AC myself, but I can't find the low pressure valve/fitting help?

any pictures or diagrams will be helpful!

Thanks

Forgive me for the lateness but.... Here's the outcome

My husband MADE ME take the car to Volvo ta have it looked at AND...

The oil PCV pan was clugged up! it cost me $480 to fix. That was the only thing wrong with the car....it just caused all those other problems i.e. car cutting off in idle ...

Would the wrong oil cause the problem?

Up above I listed the chain of events!! pray for me! lol

I questioned the car cutting off because....

While at a low rpm the sometimes cuts off! It will sputter and then cut off, however, it will start right back up!

1) I used the wrong gas in my car (regular)... and that blew 1 of my 02 senors. I went to autozone and they ran the check engine light ...

the car has 89,000 miles on it I bought it used in April

I went to Volvo dealer in Maryland; I was told I need to have the PCV system replaced because it's clogged.... Volvo want 520 bucks!
(It was causing the whistling sound i thought was the serpteine belt!!! they said this could cause the car to cut off)

My question is can I take it too Midas? or ...
