I have one of these and I use it constantly. Maybe I should buy a couple more. One to keep in my truck and an extra to keep at work. So all you newbies you come on the forum and go "My car trouble light is on and whine whine whine" do yourself a favor and buy one.

Then you can post my car has "P0303 code" and we all will be more than glad to help.

It's not like I am being snarky or anything like that.
