That can do a compression test in the so cal area.

 

I would imagine most shops can. Or you can always go buy your own compression tester and do it your self. Its pretty simple.

 

so i buy a cheap one from like autozone or what. I know it involves connecting it to my spark plug housing tube thing. But how do i get a car to start when its going thru such p0300 horrible codes involving starting. Link me a Test i looked up compression and leak down. Which is more cost effective.

 

You can buy them at any auto parts store.
Here is a pretty decent video....

 

Check out the SoCal page sticky "Recommended Shops." You'll find one close to your home....Gary
