HOW DO YOU CHECK TO SEE WHICH COIL PACK IS BAD ON THE CAR?
To check the coilpack just get a test light ground it some where on
the block then press the the test light on the head of each wire at the
coilpack. You should hear a change in the way the car idles, if you get
to one of the wires and the idle does not change, that is the cylinder
that is giving you the problem; but it could be dead cylinder and not
the coil pack.
In other words...
1. Set the dial on your voltmeter to "Ohms."
2. Touch one of the leads on the voltmeter to one of the electrical terminals on the coil pack. There are two terminals: one on the top of the coil pack and one on the bottom. It does not matter which lead from the voltmeter touches which terminal on the coil pack. Then, touch the other lead on the voltmeter to the other terminal on the coil pack.
3. Check the resistance. The display on the voltmeter should read between "0.0" and "0.05" Ohms. If it reads higher than "0.05" Ohms, then you need to replace the coil pack.
Hope helps (remember rated this).
