Is the Malfunction Indicator Light showing and have you checked for trouble codes?

Most parts stores provides free scanning services. Without retrieving the trouble code you are working blind and hoping that replacing something is going to solve the probleem which is not the correct procedure and can be costly and time wasting.

A misfiring cylinder can be due to spark plug, compression, ignition coil, fuel injectors or wiring to the injector or coil. It could even be a bad computer. You should ahve swapped the coil instead of replacing it. If problem migrates, that would indicate a bad coil.

100 psi seems to be low for compression readings.
