Whaaaat? You mean I m NOT the only one in your life that your spending time on? WELLLLLL! Of all the nerve! :-D (and here I thought I was special and not just because I rode in a short yellow bus) :-D
I appreciate the check in from you . But I never lost faith that you d be back here whenever you could I kind of figured hoped :-D you had a life outside of just staring at your computer monitor reading my rambling messages :- )
Speaking of rambling: here's more.
The truly annoying thing about this vehicle is that it is almost like the designers were experimenting with the newer computerized technology that was JUST starting to be imagined (and would-sadly-become a standardized design for the later years) while still keeping some of the old mechanical elements intact and they seemed to have mixed and MASHED both type of components all together into this vehicle and probably other ones too, during this early 90 s era .(Some parts in this car just don t make sense as to why they re here when coupled with basically electronic/computerized components, too)
But anywhooo I ve come across a couple of things as I ve been surfing the web; trying to come up with some answers for US :-D
1) I found a more close up pic of the underside of THAT part YOU found for me and as I zoomed in I could see something of a spring /screw type drive system inside AND I came across a youtube vid of some other vehicle (totally different make model, etc think it was like a Silverado Pick up or Jeep or the like) and the type of IAC they were showing was similar with no electrical connection.
But in order to repair it the person in the vid had to remove the brass end cap and inside was a flattened plastic looking disc with a couple of slots cut across it and by placing a flat head screw driver in one of the slots he rotated the disc till it was wound back downward again essentially he seemed to be resetting the? To its most effective (or original) level . Don t Know IF this is what WE got inside of our valve or it s something else entirely .
2)I also found (by accident) a geo metro forum which seemed to show in one of its threads, an IAC valve, that looks amazingly like the VERY first pic I posted above in this long thread and their thread went on to describe how they gently pulled back some of the SMALL metal hasps that were surrounding the top and removed the top housing where those hose connectors were and revealed a type of piston inside see the pics I attached below with this one)
Sooo I ll do a little bit of on car investigation this weekend to re-look at that component I posted a pic of first above (but prolly not much else in regards to removing the TB and getting a good clear visual on OUR IAC valve, cuz I won t have access to getting a TB replacement gasket should I find I need one after my gorilla attempts to remove the TB just to be on the safe side) AND, of course I ll definitely keep thinking about this, looking and reading also .
Since you've got waay more experience, expertise AND resources I'll definitely look forward to what you've been able to discover. BUT. BUT. Please know only as you're life allows and at your convenience. This isn't a "hair on fire type of emergency", its turned more into an annoying, but fun(?) Type of obsessive challenge.
HAVE A FANTABULOUS WEEKEND Saturntech9. Rest well (when ya can) and play often.
Chat with ya later and thanks again for ALL of your thoughts and efforts.
