It does have treatment added.

I'm starting to wonder if it isn't the ecm giving me a fit. It was in the upper 50's/low60's this morning when I fired it up and it was running high idle as it should. Other mornings that are colder, it barley wants to idle.

No I haven't Ken. I'll give it a check.

 

Howdy folks. I've been busy with the new job, so the 91 has been put on the back burner for a while. I think I might have found the cold start issue. I replaced the ignition control module and the old beast seems to be running even better. I guess I'll find out the next time we get a cold enough snap to fully test it.
