opti trouble

Not always constant misfire , a few times mine will run normal for a day to a week and usually misfire or stall more and more often for up to a week to a month sometimes before crapping out for good , IMO a good rule of thumb is misfire=opti as long as plugs,wires,coil, and ICM are good.

I always changed both the Opti- and the -Spark when I experienced the following symptoms:
* Car suddenly dies and won't restart
* Starts but immediately dies
* Extended cranking to start
* Rough idle
* Sputtering
* Backfiring
* Trouble reaching higher rpm
* Black smoke from exhaust
* Poor performance with car warmed up
* Weak plug wire spark
* Codes 16, 36, and/or 42 ... I dunno the OBD2 equivalent codes

I haven't yet learned how to tell when I only need to replace the -Spark vs when both the Opti- and the -Spark need replacing, so I just do both ... but there is supposed to be a way to tell ...
