It worked for me.
on January 2, 2008
I bought this to diagnose a misfiring cylinder. I had the same problem previously, and the dealer charged me $400 for diagnosis and repair. With this one use, I "broke even".
The code scanner worked well. The graphing feature is of limited use. I'm hoping future software updates will make it more useful. You can't press the buttons too quickly, or they won't work. I had to call the "help line" to install the driver so my computer could recognize the scanner via the USB cable.
