What is the difference between an ignition coil and coil pack?
The ignition coil is a device which is capable of generating a high voltage pulse which goes to the spark plug. Coil pack refers to the set of coils used in the engine which do not run a distributor. A computer controls the set of coils. Each coil will supply power to the individual spark plug or a set of spark plugs.
Should I replace all coil packs at once?
Coil packs are reliable and likely to last the lifetime of a vehicle. If anyone goes bad, there is no need to change all of them. However, if one pack starts malfunctioning after the odometer has around 75,000 miles, you should replace them all.
How long do coil packs last?

What causes engine coil failure?
The overheating of ignition coils can hinder their ability to conduct electricity. Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.
Will a new coil pack improve performance?
You cannot expect aftermarket coils to increase the horsepower, reduce emissions, increase gas mileage, or smooth out your engine’s performance without having the coil removed in the stock car.
Will changing ignition coil improve performance?

Can you replace one coil pack?
You can, of course, change just one coil. However, as a mechanic, I’ve seen it so many times, when one coil fails, another isn’t too far behind. If your coils are easy to access, replacing them as they fail is OK, apart from the inconvenience. It is possible to drive a car with a faulty coil, but it isn’t advised.
Can you replace ignition coils yourself?
You can replace a failing ignition coil fairly easily at home, but remember that you’re dealing with high voltages so must disconnect your battery before you start.
Are cheap ignition coils any good?
While low-grade coils cause misfiring and difficult starting, using them can have more serious consequences. As coils are controlled by the engine management computer (ECU) they rely on fly-back voltages that are fed back after the spark plug has been ‘fired.
How do you check the coil pack on a Jeep Cherokee?
Press the left ohmmeter lead against the center prong inside the electrical connector on the back of the coil pack. Press the other lead against each of the spark plug boots, one at a time. The ohmmeter rating should be below 2 ohms. If the ohmmeter rating is above 2 ohms, replace the coil pack.
