How do you know if the coil pack is bad in 2002 Mitsubishi Montero Sport?

If you have misfire codes you swap the coil you think is bad with another coil, clear the codes and drive the vehicle until the CEL lights up again. Then check the codes to see if they changed to the cylinder you moved the coil to.

Car is misfiring or will not start. Check for spark with a spark tester at the coil pack. No spark, check for constant power and signal power. Constant and signal power is good, the coil pack is bad.
