David, I never said that an alternator feedback problem would cause dieseling.
All I am saying is that I had a problem with a vehicle doing this thing that resembled dieseling in every way, shape and form, and it was actually running on one or maybe two cylinders.
It knocked, smelled terrible, and so on.
Had all the symptoms of dieseling, except that I could start it cold, run it for only two or three minutes and it would do it.
And, in my case, replacing the alternator fixed it.
I share the same sentiments as you expressed, with many posts on many forums. However, the mere fact that someone here (me) says it was the cause of a similar problem as the original poster described, and both you and I have found references to it on forums this evening, should make you go "Hmmm, maybe there is something to this.".
