As it turns out, my car does not have breaker points in the distributor. It has some sort of wheel with six "petals" and an electronic eye which seem to satisfy the function that mechanical breaker points normally would.

I did find that a jumper wire inside the distributor, a ground wire I believe, was quite frayed, so I removed the distibutor and resoldered it.

Also, the vacuum advance hose is not used, a detail which I had forgotten about in my earlier mail. I attempted to reconnect this some time ago and found that the engine would not run properly.

On the driver's side inner fender wall are mounted two finned alloy boxes. One is a Bosch item (p/n 0227 051 014 I believe), the other is smaller with the name Lumenition embossed on it. The wires from this box connect to the distributor. Anyone have any info on this piece?

After the distributor r&r, I started the engine and let it idle for a while. After it had warmed partially, having idled smoothly and steadily the whole while, it again stalled suddenly as before. I was able to restart it and the cycle was repeated several times. It occurred to me then that the stalling seems to only occur when the engine is partially warmed. If I am persistent and keep restarting it and it gets fully warmed up, it no longer exhibits the stalling behavior. I have in fact driven it all over town on warm day without incident.

So, I am now wondering about anything that might be active during the warmup cycle. What are the functions of all the sensors on the passenger side of the head? Are there any other sensors or warm-up cycle functions that might fail in some way that might cause sudden stalling?

Thanks in advance once again.
