OK, so I did a search and I think I have the answer. I just wanna make sure.
87 Renix 4.0L in the last month or so has been giving issues at startup. Will run for maybe a second or two then die. If I give it some throttle for a minute or so at startup it will run fine from there.
So I've checked the vacuum lines, cleaned the throttle body, checked the plugs, fuel pressure, etc.
Started it and it still does it.
So I pulled the harness connector off the IAC and started it. Ran fine. No problems.
My take from reading about 300 posts in the search for IAC stuff is that I need a new one.
Would like a 2nd opinion before I do it.
