[QUOTE="kingb1973, post: 356116, member: 5649"] Sounds like you have a very original car to start with. Always a good thing. Can only assume that if parts were there, they were there for a reason. I don't have a lot more to offer, but.... Went back to the beginning of this post and re-read that you have AC. Missed that originally. I never had AC so didn't give it a thought. Perhaps the reason for the 3 port valve? Nothing to do with emissions? [COLOR=#333333][FONT=Tahoma]Came across this today. Old post discussing the DVCV and how it relates to Idle, AC and other loads, and Temp.[/FONT][/COLOR][FONT=Tahoma][/FONT] Worth the read, good information from others. Explains the need for the 3 port valve.
