Solved the mystery. Appreciated the help.

Looking at the WD's, I don't see a physical path between the dist to the coil, except thru the ECM... as I would expect. Because the transistor on the coil amplifies the dist pulse via the ECM, and not directly from the dist, I believe your problem would likely be on the coil side of the ECM, wouldn't it?.... maybe even the transistor itself, or possibility the (gulp!) the ECM. Personally, I'd suspect the tach signal source wire. Have been under the dash yet? BTY Hoozie, what years CAS will interchange on my '87 SPFI - EA82? Wire colors are obviously different between some years, but what about potentual differences in the opti triggers? '87 supplies here in Idaho appears to have dried-up. I might need a ECM also as i'm getting 500mv from the (body side) of the CAS connector (the black wire). Thought it was suppost to be a ground? ~putt~

My kinda guy.. Much appreciated Hooz. I have a Haynes... but it's woofully inadequate..

Is that a guaranteed fix?

I have a 1987 GL 1.8 OHC w/TBI and CAS ignition. Two weeks ago, it started dying suddenly - cold or hot - in town or hiway, no specific pattern. A successful re-start can take 45 seconds, or as long as 5-10 minutes - very unpredictable. What's interesting is that when the engine dies, the tach also dies. The problem is also becoming more frequent, dying 2 or 3 times in less than 5 miles. A friend pulled codes 11-13-14-24-33-34. Of those, code 11 says "crank angle sensor/circuit" and code 13 just says ""crank angle sensor". What's the differences between these nearly identical codes? Wanting to be sure about the correct fix, I have a couple of questions: 1. Armed with a DMM (digital multimeter), how can I verify the CAS is defective? 2. IF the CAS is bad, what other years, models are *possibily* interchangable? I ask, because locating a 1987 crank angle sensor, has been unsuccessful so far.
