Ok, car died on me Sat and hitched a ride home on a flatbed. It was running fine to that point, then died, it was dieseling when I got it to the shoulder. I have spark from the coil but none from the plug wires. Seems like opti time, any opinions?

Pretty good bet. I'd pull the cap off the Opti and see if the rotor is still in one piece. More than one person, self included, that has auto-x or used their car on road courses has had the rotor screws back out and the rotor sit loose on the distributor shaft or self-destruct.

The rotor on mine exploded exiting a turn at 100+, while door-to-door with a few other cars. Made for an interesting ride but fortunately a safe coast another 1/4+ mile to pit row.

Come to think of it, there were a couple of backfires involved.

I just went through this too and it ended up being the ICM . I checked spark with a inline tester and no spark so I figured it was my Opti, last year when I replaced it I didnt locktite the rotor screws and figured it must of came off. sure wish I checked the ICM first before I took off everything, oh well now I get the chance to use the locktite.

Have a lifetime replacement on the icm so that's one of the first things I did. I have spark off the coil but not the opti.

Yep, this is why it wasn't the ICM

If spark is going into the Opti but not coming out.....
