So after lots of tinkering with my '93 wondering why it was shutting down I finally decided to swap the opti just to see if it made a difference. I had a barely used MSD in the garage that I fixed up for the job, installed it and varoooom, it started right up and...hasn't stalled since.

I can't even remember who I bought the Chinese opti from (someone on eBay), but for the record it had around 1500 miles on it before the stall-outs began. Up until then it ran perfectly. There was no 24x, no codes, just complete loss of ignition when the engine got hot. Funny thing is, it would always start right up afterwards. This was the opti with the black cover.
I had to know how long a cheap opti would last. I guess I know now.

I originally took out the MSD because the housing kept rubbing on the rotor and causing a 24x. I glued the housing down and I'm hoping it will last the summer until I can shell out the $400 on a Delco.

I read the title and already knew where this thread was going.

Speedy - Would you mind taking apart the eBay opti and posting a couple pics of what the failed optical sensor looks like? Thanks!

I took a chance and bought an opti from Autozone, for which I can only assume was of Chinese craftsmanship because with one revolution of the rotor and all the scary noises that came out of it, I had to tell the parts counter person, "Oh hell no!" and got a refund.

Okay, here's a pic of the Chinese optical sensor (on the right) compared to an old Mitsubishi sensor from the AC Delco unit that came with the car (that still worked at 85,000 miles). Disregard the green paint dot on the Delco sensor. The two are very similar, but note the Mitsubishi logo on the Delco unit.

Well I am having the same exact problem you described speedy, the car randomly dies when hot and immediatly starts back up with out giving any codes. But the strange this is I have been using ac delco optis, I just now sent my recently bought delco unit back to summit for another ac delco unit hopefully this works. It's just wierd the you described the same exact problem that I have been dealing with since november

Are you sure that your problem is the optispark?

I have literally checked everything at least twice if not three times. Alot of people have told me to check the ICM but since I run Bobs LTCC and It does not use one.

Get yourself an AC Delco opti off of Amazon...it was much cheaper then 400 dollars! Been working great ever since install!
