Symptoms of a 1998 dodge stratus bad coil pack?
symptoms are: you can hear the engine missing, spitting and sputtering, loss of power...you can tell if it is a coil pack by unscrewing the spark plug that it connects to coil pack. when you look at your spark plug it should be a light grayish, white..this means the coil pack is working....it is best if you do this with new spark plugs, because your spark plugs could be bad. but you do this process until you find a bad plug then, that coil pack probably is the bad coil pack.

How to troubleshoot bad coil pack?
Auto Zone or other parts stores should be able to use an OBD II reader to diagnose the problem and tell you which coil pack is bad. Replacement is simple. Simply remove two screws and replace the coil pack. I just went to Auto Zone to have the modulator checked on An '87 Maxima and they told me it wasn't in their book.
What is a coil pack?
Your truck has two coil packs. one on each side of the truck. I changed mine twice on my 99 expedition. I dont know the exact definition of the coil pack, but i know that they are related to the sparkplug and it's wires, and when they go bad they can cause a misfire with the sparkplugs. If you need to change them send me a message i can tell you how.

How do you get to and change the sparks plugs on a 2002 Grand Cherokee 4 liter?
If I remember right. You should have coil packs covering the plugs. Look for screws holding the packs on. That should help to get you started.. There will be four 1/2 inch bolts mounted on the top of the coil pack. To tell you the truth it is easier if you take off the heater hoses from the top of the coil pack since they are in the way first. When you pull off the coil pack make sure to be aware that it does have an electrical connection that will not let you pull that coil pack to far from the spark plugs. Another recommendation is to replace your coil boots since you already did all the job. I really recommend for you to use champion spark plugs (regular resistor).
