That is highly possible on your vehicle.Especially because you have the random misfire.But first make sure the coils pass the test I post below and that there are no traces of arcing on the plug wire tubes(White marks or cracks) which is also a common failure on this engine.If you need larger pics just let me know and I'll enlarge and post it.
2.2L (VIN 4) Engine
Remove the ignition coil(s).
Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
Check the resistance between the secondary terminals. It should be 5000-10,000 ohms.
If the coil failed either test, replace the coil.
See Figures 1 and 2
Disconnect the negative battery cable.
On 1995-97 models, raise and safely support the vehicle.
Remove the ignition coils from the module.
Remove the module from the assembly plate.
Installation is the reverse of the removal procedure.
