Code 215 Distributorless ignition system, coil # 1 did not have an ignition diagnostic monitor signal for every electronic spark timing, SPOUT, signal sent by the PCM.

thank for the reply discnik how would i go about fixing this issue is this caused by the icm or the coil pac this car has been a pain the miss come a go's and my scanner pick up nothing cly bal test checks good some time no code but the miss fire is happening more often

It shouldn't cause a primary coil code, but the spark plug well gaskets are known to allow oil to leak into the plug wells and cause a misfire. I'd suggest you pull the spark plug boots and inspect for oil. If you find a well or two with plug wire boots that show signs of oil, you'll probably want to repair the leaks before spending money on a coil or ignition module. Of course, while you're there, you may as well check the spark plugs and replace them if they are due. It's possible, but not probable, that either of these could contribute to the code.

If both of these are fine, or they don't cause the code to go away, then you'll almost need an oscilloscope to backprobe the signals to and from the ignition control module (ICM) to see where the problem lies. The ICM supposedly is getting hard to find. I have one that I bought for my '93 SHO ATX before I sold it. I suspect the ICM for the ATX is the same as your '92 MTX. Let me know if you think you need it.

I sent you a Private Message regarding the module.

As for the misfire, is this the car that we've discussed the Crankshaft Position Sensor (CKP) signal before? Have you checked the CKP signal? How about the Camshaft Position Sensor (CMP)?
