Launch X431 Pro Mini Power Balance Test for Ford Lariat

I have a misfire on my 2005 Ford F150 Lariat, so what I want to do is to use a Launch X431 Pro Mini bidirectional scan tool to perform power balance test for the car. Now I will get to start:

Connect the X431 Pro Mini VCI module to OBD2 port of car, go access to main menu to press function buttons.
Tradition Diagnose >> Ford >> Submit >> Automatically Search >> Set ignition switch to ON(Position II), press “OK”>> Yes

As you can see, there are 8 cylinders. I will put on a little load, put it in drive off, then put my foot on the brake and give it a little gas.

Now you can see No.1 misfired, see how it shot down I can also fill it in the truck. On the No.8 is shot down just at the end because the one getting ready to fire.

Launch X431 Pro Mini is one of the best diagnostic tools to show No.1 has a problem, it turned out to be the coil pack was breaking down. I am going to fix it.
