I know I have, now I just need replace the worn out hoses in the engine so I can stop having those tiny vaccum leaks, and I need to eventually replace the AFM, but for right now the car is running like a champ and thats all I care about :D

Side note: talked to my mechanic this morning and he was like wow!

Very cool.  I never knew this feature existed.

BTW, where is the idle speed CO potentiometer located?

It sits on top of the air flow sensor. Pages 13-52 and 53 of the referenced manual.

Now I understand how my car runs without an O2 sensor:o

I had this same problem! However I just took the casing off that part of the wiring harness when I was trying to get at the blower motor and saw that those two wires were disconnected....so I connected them...put everything back together and got shitty idle for a long time and engine cut offs. Until I remembered I had attached that wire, I unattached it and everything went back to normal, never figured out what it was though...until now...I am still kind of unclear though....what exactly does it mean when it is plugged in? It says that is for when the Catalytic converter is not installed? That doesn't make sense to me, because I have no Cat on my exhaust, and it still runs like shit with it in....anyone care to explain it to me in simple minded terms? =P

anywho....I'm leaving that wire disconnected. ^__^

Well I'm just glad my car is running well again and that I was able to help so many people get their cars running well again. I've certainly received enough help and good ideas here.

What a silly thing this was, I have a thing about disconnected wires and just hooked it up when I saw it disconnected without further thought.

Took a while to notice the hot start problem, it seemed to just get worse and worse, it wasn't a sudden change. Did anyone else notice that it took awhile to get bad or is it just my imagination.

Anyway, it appears to be fixed and I'm putting tape over those connectors so I won't have another brain cramp and hook them up again!

Happy stumble free driving everyone!

Wow. Good work sports racer.  I don't have this problem but have been following other peoples search.  Hard to believe it was something so random. Well done.

+1 to sticky this, or move it into a list of common problems/fixes where it will be easy to find.

Fixed. When I saw the solution post Thursday night, it was 2am and raining, but I grabbed a flashlight and ran out in the rain to try it. This infuriating problem has been driving me insane and keeping me from liking this car. Thank You!

Before I do this today, what is the point of this wire and what is it telling the car differently then it was before.  I will be the happiest dude alive if I could fix this problem.  Just let me know what this wire does first.
