Thanks for the offer Philip. It is nice to know you and thanks for the help. I drove down to the pecan festival today and it was nice to open her up on I-19. Speed Limit 75 - traffic flow 85. There were pick up trucks and SUVs passing me at 85! The car performs great on the road. The idle is irregular and for the most part is somewhere between 1000 and 1200. It did get stuck up at 1500 rpm so, I have decided to look into the brushing service from DCS.
http://www.crossfireinjection.net/about_us.htmI think it will be a while before I send them in but, I have an inquiry in with them. I will let you know what I find out. One can send in the cores and get serviceable replacements or request return after service of my original cores. I have not checked for matching numbers on this car but, the previous owner gave me all the information he received from the original owner. The biggest thing replaced was one of the bronzed T-Top after a break-in event.
I thought I had a place to send in the complete units but, does not look that way on my recent searches. I'm still reading and learning on the CFI Vault page. The DCS site also has some information available under the "How to" section. I will post what I find out. I'm thinking that cleaning the IAC won't hurt. Thanks again.
