Hello,

It sounds like you lost one of the coil drivers inside the PCM or the distributor is bad but to be sure lets check the wiring to the coil to confirm the failure.

Here are the engine wiring diagrams. Does this car have a distributor?

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken

Did you check the wiring? Also, the driver module is inside the PCM did you change it out? If you can read the wiring diagrams I can give you larger ones.
