So have you changed both plugs and wires for this coil? You said you changed the plug that goes with it but you have two coils, one for two of the four cylinders. Then another coil for the other two.
More then likely you have a short somewhere causing the coil to operate inappropriately which causes it to overheat and melt. This is either a plug, wire, or an open circuit on the ECM control wire causing the coil to overheat.
We need to monitor the control wire with a lab scope to see if there PCM is pulsing the coil when the plug is supposed to fire. A meter will not be fast enough to see the voltage drop. If there is just constant voltage then we have a short and most likely have damaged the PCM. I suspect we are going to have to replace the part that is causing the short and then the PCM as well.
Let's start here and see what we turn up. Thanks
